Mini Pause #117 | What Training Gave Me

Posted on April 11, 2026April 10, 2026 by stephanie-estima

I originally got into training purely for aesthetics.

I wanted a tiny waist and glutes that left the room two minutes after I did.

And I did that.

But I stayed.

I stayed because of what lifting gave me.

Lifting taught me how to love myself. How to give myself grace.

How to be in touch with my body and be patient with myself.

How to be proud of myself for doing very difficult things.

These are skills and qualities I wasn’t given as a child.

Strength training helped me become the parent to myself that I always needed.

(Let that sit for a minute.)

Before training, my body was a scary place.

It felt like an overwhelming sea of emotions and trauma waiting to drown me.

It was safer to stay in my head. To calculate everything so I could control everything.

I treated my body like a vehicle that carried my brain around.

Training changed that.

It taught me how to feel my feelings and accept my body exactly as it is…

Because the gym is democratic. Weights tell the truth.

45 pounds has always been and will always be 45 pounds.

There’s no supplement, surgery, or shortcut that will build muscle for you.

All you can do is pick up that heavy shit and let it confront you.

[💪 LIFT will get you there, whether you’re brand-new or have been lifting for 20 years. This is the strength training program I follow to this day.]

That weight doesn’t care what you’ve been through… or what you’re going through.

A dumbbell doesn’t care that you had a different outcome in mind.

The barbell has no sympathy for your stress or the demands on your time.

The weight will be there for you. Consistently forcing you to reckon with your body as it is.

And that’s what I let it do.

Even if that means letting my body shake for a minute after a set… even if that meant unexpectedly bursting into tears after squats.

For me, strength training became a way to process the difficult things I could remember… and eventually the things I couldn’t remember but knew lived in my body.

[✨ No weights available today? Use push-ups to get that release.]

It gave me a path back to my body being my own.

It helped me feel safe in my skin.

That process of building a relationship with your body matters far more than any waist-to-hip ratio, glute pump, or clothing size ever could.

So yes, I love the way I look.

But to get here, I had to learn some really hard lessons about loving myself when I didn’t like what I saw in the mirror.

I had to learn to love myself when I felt ugly, unloveable, and unworthy.

More than the way I look, what I really love now, at 48, is how I feel inside my body.

I love the pride of knowing I did this. On purpose. By myself.

I built this on the days I didn’t want to train.

I built this even when the workout was awful.

I built this even when I didn’t feel like I was worth the investment.

I built this for myself – and for Baby Stephy, who came along for the healing ride.

No one can sell you that kind of pride.

You earn it.

You gift it to yourself.

If you’re in a season where training feels slow, confronting, or deeply humbling, I want you to know that this is often where the real gifts are.

Not just in the body you build, but in the relationship you build with yourself, and your inner child, along the way.

Mini Pause #116 | It’s actually not just your hormones

Posted on April 4, 2026April 2, 2026 by stephanie-estima

I almost spit out my coffee this week when I was reading a research paper.

(I said almost. I didn’t want to waste my coffee – but I definitely paused mid-sip… a bona fide Big Deal for this caffeine queen.)

The paper stunned me because it confirmed something I’ve been saying for years:

Hormone changes don’t automatically cause fat gain.

So many people (influencers, advertisers, TV shows, your own mother, your own DOCTOR!) claim the opposite. They want you to feel relieved that it’s not your fault and there’s nothing you can do. Congratulations! You’re off the hook!

But they’re wrong.

The science officially proves that you’re very much on the hook. You have more control than you’ve been told.

And before you bristle at that – stay with me.

Because this isn’t blame.

It’s leverage. It means you have options.

Women have passed a story through generations: Your body changes when your hormones change.

Nothing you can do about it. Happened to your mother, happened to your grandmother, gonna happen to you.

“It’s my hormones.”

It’s clean. Simple. Convenient.

Also wildly incomplete… and extremely profitable.

See, Betty, if estrogen is the villain, you can’t be the heroine. You have to be the patient.

You have to wait for someone or something to save you (from your own biology?)

You have to accept. Comply.

And listen – I am not anti-hormone therapy. Not even a little.

[✨ Grab my free HRT Guide, which includes questions for your doc.]

But I am deeply suspicious of anything that removes a woman’s agency and calls it empowerment.

What I See – Over and Over Again

I see women who are doing everything “right.” Classes, cardio, clean eating, light weights that never dared to get heavier… and yet her body feels soft and unresponsive to all the effort.

→ She tells herself, “It’s my hormones.”

I see women who used to be consistent but lost their footing somewhere between career, kids, aging parents, and exhaustion. She wants to come back to herself but feels discouraged now that her body is changing.

→ She tells herself, “It’s my hormones.”

I see women who train really freaking hard – lifting, sweating, pushing… but who under-eat and push harder instead of recovering because they’re trying to do better than their mothers…

→ Who told themselves, “It’s my hormones.”

And then I see women who have figured it out. Who lift with intention and eat to build. Who take recovery seriously and defy the idea that she can’t be exactly who she wants to be because of her age.

→ She refuses to tell herself, “It’s my hormones.”

Betty, if you see yourself in one of these women, I want to encourage you:

These are not four drastically different women who are genetically programmed to get different results.

These are four different moments.

And they reinforce exactly what this research paper proved.

Women In Perimenopause Are Not Hormonally Broken

I’ve seen this clinically for over two decades.

Women enter their 40s with:

Low muscle mass

Declining bone density (yes, already!)

Compromised joints, tendons, and ligaments

Years of under-eating

Stress that never fully resolved

Less movement than they think

Estrogen changes don’t create a new problem.

Estrogen changes expose the problems that used to tolerate being swept under the rug.

Start with Muscle

The single most important step you can take to rise above hormonal fatalism?

Build muscle.

Muscle is metabolic currency.

It determines how your body handles glucose.
Your bone density.
Your joint support.

Without actively building muscle? Everything downstream gets harder… and it’s not because you failed.

It’s because you were never taught how important muscle is.

It’s a loop.

Less muscle → less movement → more fat gain → less desire to move

And around we go.

Add in joints that hurt, tendons that don’t tolerate load, and a fried nervous system… and suddenly you stop being able to push yourself into results.

… and you start to believe the lie, “It’s my hormones.”

We didn’t get here by accident, Betty.

We were trained up real good through years of:

More cardio
Less food
Push for smaller
Fewer calories
More “discipline”

We laid down our muscle at the altar of skinny.

Of course we did. That was the assignment.

So Now What?

You have a choice.

You can spiral.

You can bail and say, “It’s my hormones.”

Or you can step into something new.

Your body is a reflection of inputs… and you are in control of the inputs.

You can build muscle.
Not casually. Progressively. Intentionally. With devotion.

You can move daily.
Walk. Lift. Stretch. As your baseline, not as a punishment.

You can eat like your body is worth building.
Protein. CARBS. Enough food. Consistently.

You can train your joints, tendons, and ligaments.
Connective tissue strength determines how much weight your muscles can move.

You can respect recovery.
Let your body adapt to the work.

When you devote yourself to changing the inputs, your body will respond. It won’t be overnight, but it will come, and it will last.

“It’s my hormones” is not supported by science, and we have the research paper to prove it.

Our new story is: “My inputs changed, and my body is expressing that.”

In that story, you’re not waiting to be fixed.

You’re building.

If hormone therapy supports you, get after it. No judgment here.

But understand the hierarchy:

Hormones are a lever – not the entire system.

Yes to hormone therapy if that’s what works for you.

Yes, AND strength training.
Yes, AND movement.
Yes, AND enough food.
Yes, AND joint health.
Yes, AND recovery.

You are so powerful. You are the heroine of your story.

Not broken. Not late.

Under-built. Ready to be MORE.

If this is clicking for you and you’re ready to build, LIFT was designed for this moment.

This is the framework I still use at 48 to build a body that reflects the work.

[💪 Start Here]

Saluting you in your purposeful rebuild,

Dr. Stephanie

Mini Pause #115 | Protein and weight lifting are past tense.

Posted on March 28, 2026March 25, 2026 by stephanie-estima

“Lift weights.”

“Eat more protein.”

In the Year of Weird Science 2026, I can’t believe health influencers and doctors are still focusing on this as the full story.

Strength training and protein exist within complex systems… both biological and cultural.

We can’t talk about weights and protein without talking about the culture of “skinny.”

If I’m being honest, my relationship with skinny started long before I ever picked up a dumbbell.

Skinny meant approval. Control. Being “good.”

I remember being praised for it. The perception of the discipline it took to be skinny was rewarded. I chased that feeling and the validation that came with it.

Now, with GLP-1s becoming the norm, we have to acknowledge that, in a lot of ways, we’re right back where we started…

The identity of “strong woman” is competing with the identity of “skinny woman.”

I see women in midlife navigating this in real time. GLP-1s offer weight loss and smaller bodies – faster, and we’re seeing everyone from our favorite celebrities to our next-door neighbors slimming down with them.

If you wonder about them, want them, question your wanting them, or judge yourself for wanting them… let me say this clearly:

Wanting to be skinny doesn’t make you weak. Or shallow. Or a bad feminist.

It makes you a woman who grew up in the same culture as the rest of us.

What We’re Up Against

Protein and weights aren’t the core challenge for women in midlife.

The challenge for us is that skinny has been sold to us as the destination, instead of the costume that it is.

Because guess what? You can be skinny AND…

Metabolically fragile.

Exhausted.

Lose your independence at 74.

So yeah, you’ve heard that you need to eat protein and lift weights. Muscle protects metabolism, bone health, brain health, and longevity.

Got it. Read it. Saved it. Heard it on podcasts.

And yet… most women in midlife who have this information still aren’t building muscle in any kind of meaningful way. That’s the real heart of what I’m thinking about.

[💪 (and why I built LIFT)]

Muscle Is Not Neutral – It Means Something

I think the reason some women still choose “skinny” is because of what muscle represents.

When you walk into a room with a strong, capable body (that just happens to look *chef’s kiss* in that outfit), you’re broadcasting:

Competence: You understand training, hypertrophy, progression, effort calibration, and recovery, and you take the damn action.

Devotion: You show up, even when it’s inconvenient, messy, or hard.

Capacity: You can carry, push, pull, and endure… and you don’t need anyone to carry your bags.

Boundaries: You’ve made yourself a non-negotiable priority, and this booty is proof. (This one makes people itchy.)

Agency: You recognized that your body isn’t something that just “happens” to you, and so you got in the driver’s seat.

Betty, that kind of confidence makes people uncomfortable.

And good. I’m comfortable with their discomfort.

But letting go of skinny and broadcasting strength is not a one-time decision.

It lurks.

When the scale goes up from muscle.

When someone you know drops 30 lbs on a GLP-1.

In the fitting room.

On a random Tuesday when you catch your reflection at a weird angle.

It’s ongoing work – not a clean break.

The tension you feel about how your body looks doesn’t mean you’re doing it wrong. You’re just paying attention.

Culturally, we’ve been taught to reward bodies that are small, contained, and compliant with patriarchal expectations… aka non-threatening.

Even when those smaller bodies are a result of deep devotion and discipline, they still read as,

“She takes up less space.”

And that has always been easier to swallow.

A Woman with Muscle Is Harder to Place

Muscle signals autonomy, and autonomy disrupts expectations.

A strong woman can be feminine, nurturing, and soft, while also being:

✔️ Capable

✔️ Self-directed

✔️ Resilient

✔️ Assertive

✔️ Very aware of what she brings to the table

We’re much more comfortable with those traits in men… so it’s disruptive.

[✨ Nail 3 of the Muscle-Building Moves I Swear By]

Why You Feel Resistance

Building muscle requires you to take all the information you have about weight lifting and protein and turn it into an identity shift.

Identity doesn’t change because you get new information. It changes because you take consistent action to do the thing… often before you feel ready. While you’re still wrestling with skinny.

Taking the actions necessary to chase muscle instead of skinny requires you to become someone who:

Eats more – not less

Lifts with intention

Recovers like it matters (because wow does it ever)

Keeps promises to herself

That’s identity work. Every rep confirms your devotion to the person you are becoming.

You might be used to evaluating choices in the context of, “Will this make me smaller?”

I want you to start asking, “Will this make me MORE?”

More capable. More resilient. More energized. More stable.

We’re not abandoning aesthetics. (In fact, it’s something I care about a lot!)

We’re expanding what you’re allowed to want from your body.

So Here’s the Plan

If you’re still trying to “tone” (a 4-letter word in the Bettyverse), shrink, or lightly sculpt your way into a skinnier body… you’re working inside an outdated model.

The new model is: Build at all costs.

Build muscle.

Build capacity.

Build strength you can see in the mirror.

Build a body you can count on to carry you through the next 40 years.

As a builder…

You lift with structure, not randomness.

[💪 $97 gets you LIFT and everything in it – the exact program I follow to this day]

You eat enough protein to support growth.

You hydrate properly so your muscles can actually perform what you’re asking of them.

You take recovery as seriously as you take movement and nutrition, so your body can adapt to the stimulus of weight training.

You become someone who demands the space they’ve earned in every room.

Muscle that looks incredible today and holds you up into your 80s? That is built by considering the full system of what got us here.

The Bottom Line

Fitness and medical influencers would have you believe that the Big Question is:

“Should I lift weights?”

But it’s not. You already know the answer to that. Of course, you should. We all should, whether our goals are aesthetics, lasting quality of life, or both, or MORE.

The Big Betty Question is:

Are you willing to become the woman who leaves skinny behind to confidently build and maintain muscle?

Are you willing to be a person who takes up space? Who signals capability? Who stops shrinking to belong?

Muscle is going to change the way we look, and I love that for us. But it also changes what we broadcast. Without saying a word.

And that… that’s the real play.

Mini Pause #112 | She asked me for my secret to a flat tummy and big booty

Posted on March 7, 2026March 5, 2026 by stephanie-estima

A woman came up to me at the gym this week and asked me what I was doing to get a flat stomach with such a big booty.

(And I was like, hold my beer intraworkout ketone drink¹ and let me tell you!!)

She told me that she had been struggling for years to get rid of her belly and grow her glutes, but was finding it incredibly hard and frustrating.

After channeling my inner Nancy Drew, I solved the case:

She just turned 40, and the strategies she used to rely on for weight management don’t work anymore.

She eats 1100 calories a day.

Her only activity is her hour at the gym.

She sits at her desk for the rest of the day.

The Verdict: Girlfriend is STARVING.

I told her about my lifting program to show her what I do in the gym, but I had to be honest with her… most of the things I swear by to get results are centered around recovery.

Recovery is not a break from the work.
Recovery is the work.

I gave her the rundown on devoting myself to repair as much as (if not more than) my workouts:

I eat carbs! Breads, potatoes, rice, fruit… bring it all on.

I get sufficient protein and supplement² with protein powders to be extra sure.

I eat ~2000 calories on leg days to build that peach.

I sleep in a haven³ with my cold, dark, silent bedroom.

I walk daily⁴, aiming for 10,000 steps.

She really seemed resistant, especially to the idea of eating more carbs and total calories, and I felt for her. Once upon a time, many moons ago in a land far, far away, I was her.

And even though I’ve been living, breathing, and teaching strength and muscle growth for literal decades, that old programming still pops into my head every now and then.

No matter what you know to be true, it can be tough to completely silence the burn, burn, burn mantra we were taught as young women. Get on that damn elliptical and punish yourself with repetitive, boring, steady-state motion until you’ve earned back the calories you dared to spend on lunch. Push yourself to get smaller.

Now that we’re grown-ass women dedicated to building bodies that will carry us as we age, we need to right the ship.

Repeat after me: Muscle doesn't grow in the gym, it grows when you rest it.

[💧 Start your recovery with my Hydration Recovery Cheat Sheet]

Recovery is the ultimate tool for body composition and building a body that feels safe to inhabit… and it’s not just about your muscles.

There are 4 types of recovery to consider:

Muscular Recovery
Muscle protein synthesis peaks roughly 24 to 48 hours after resistance training.

If you’re new to training or coming back after a long break, it might take longer to reach that peak. For the Barbell Bettys who are training regularly, you’re looking at 1-2 days.

If you train the same tissue intensely every day, you interrupt the repair process that makes muscle grow.

👉 Do this: Strength train with a 4-day split. You give your main working muscle a solid week off between focused training days while you work on the rest of that bod.

Connective Tissue Recovery
Tendons and ligaments adapt more slowly than muscle. Collagen turnover is slower. Blood supply is lower.

It’s why your quads feel like they could push more weight, but your knees are the limiting factor in your squat.

It’s why your glutes feel fine, but your gluteal tendinopathy doesn’t. (If you’ve never had the pleasure of experiencing this, I’m thrilled for you – this is one of the most common, chronic, and excruciating tendon injuries in women over 40.)

👉 Do this: Distribute your protein across the day, eat enough carbs to support tissue remodelling, and avoid fasting before a strength training session. Give your body fuel to work with!

Nervous System Recovery
High-intensity intervals, heavy lifting, and chronic stress all activate the sympathetic nervous system.

If your resting heart rate is elevated, HRV is chronically low, and you wake up at 3:17 a.m. wide-eyed… Betty, you need a break.

👉 Do this: Add deep breathing, restorative movement (think walks, yoga, stretching), weighted blankets, essential oils, massage therapy, cuddles with someone cute, or a cup of chamomile tea. Not every day is a Norwegian 4×4!

Hormonal Recovery

Undereating (1100 calories is definitely undereating) + overtraining = increased cortisol.

Chronically elevated cortisol impairs thyroid conversion, disrupts progesterone, and worsens insulin sensitivity. As women in midlife, we have enough hormonal math to think about. Cortisol is something we can get a hold of.

👉 Do this: Eat. (Ahem… sorry, let me try that again…) EAT! Food is fuel. You can’t make something out of nothing. When you tell your body you’re starving, it will behave accordingly.

[✨ Grab my free Carbs + Protein Cheat Sheet.]

Bottom Line: You don’t get a sticker for running yourself into the ground.

You get your Bounceback Betty status when you prove your devotion to your 80-year-old self by learning how to recover, adapt, and grow.

¹ Use code BETTER for 25% off clean, caffeine-free ketone drinks at Kenetik.

² Use code BETTER for 20% off your first order of the tastiest Equip protein.

³ Use code BETTER for 20% off your sleep sanctuary at Cozy Earth.

⁴ Use code BETTER for 10% off my favorite barefoot shoes from Saguaro.

Mini Pause #111 | Is this insult the best you’ve got?

Posted on February 28, 2026February 27, 2026 by stephanie-estima

Et tu, Bulky?

We need to talk about this word.

Because it gets thrown around like the worst possible insult.

It’s the word that shows up the moment you add load to the bar.
The moment your shoulders look a little stronger.
The moment your jeans fit differently.

Is this too much?
Am I getting too big?

Am I getting… gasp… bulky?

[💪Quick Version: Stay calm and lift heavy.]

WHAT

First, let’s start like every great valedictorian speech, and actually look at the definition of the word…

Bulky, according to Oxford Languages, means: taking up much space, typically inconveniently.

Hmm.

Interesting that this is framed as a negative in a culture that has historically preferred women to be small, quiet, and easily handled.

Maybe bulk isn’t a problem as much as it’s an aspirational quality worth building.

Personally? I’m very happy to take up the space meant for me – however inconvenient that might be for those who want to keep me contained.

WARNING → WONDERWOMAN

The word bulky is almost always used as a warning to women:

Don’t lift too heavy.
Don’t build too much muscle.
Don’t take up space.
Don’t get bulky.

Being ‘bulky' is being solid and difficult to move. I like that part.

When a body takes up space, it disrupts systems that benefit from women being compliant and physically minimized.

Muscle changes posture.
Posture changes presence.
Presence changes how you move through a room.
It changes how people respond to you.
It changes how you respond to yourself.

And culturally… a woman who takes up space is a threat.

HOW: THE PHYSIOLOGY OF BULK

For most women, significant muscle gain requires:

Progressive overload
Adequate calories
Sufficient protein [💪My Fave Protein Powder Recipes]
Recovery
Time
And YEARSSSS (with multiple s’s) of intentional hypertrophy training.

Women have a fraction of the testosterone levels of men.

You are not going to accidentally become a bodybuilder because you lifted weights twice this week.

We don’t assume we’re Margaret Atwood because we journal, right?

We don’t worry we’ll outrun Flo-Jo because we sprint occasionally.

[🏃‍♀️Use this Sprint Progression Cheatsheet if you want to try]

I mean, I know how silly this sounds, but it’s no sillier than the belief that muscle will appear overnight or by accident.

What many women label as “bulky” is usually just water flux. Sorry it’s not more dramatic.

The muscle you train is damaged (in a good way) from the work, so it retains more water and blood while it’s healing.

I typically go up about 4 pounds on the scale after a leg day, which earns me a big self-high five. My muscles are healing and my body is adapting to being used.

And adaptation is exactly what protects you as you age.

Those 4 pounds of “bulk” are enough to make women think they’re allergic to the weight room… like this is antithetical to their goals… like lifting just “isn’t for them.”

Betty, look me in my virtual inbox eyes when I say this: That increase is temporary.

Muscle is a metabolically protective infrastructure – forever. It improves insulin sensitivity, supports bone density, protects joints, and preserves independence into midlife and beyond.

(Though no hate to the way strong shoulders look in a tank top, ya know?)

NOW

Real talk, Betty? I don’t think you’re afraid of being bulky. I think we’ve just been socialized to feel shame when we’re doing anything but shrinking.

That being said, even when you reject the “smaller is better” attitude, it can be unfamiliar to invite strength training to change your body. It’s not wrong – it’s just new, and new can feel vulnerable.

[✨New to weights or seasoned lifter? This 4-day split meets you where you are.]

So here is this week’s reframe on “bulk”:

Train to be harder to move.

Load your skeleton so your bones adapt.

Load your tendons so they stiffen and transmit force.

Load your muscles to help them grow and protect your joints.

Eat enough to support adaptation.

Rest enough to recover.

Repeat for years (not weeks).

The goal is structural presence. The confidence that comes from devoting yourself to your future by doing hard work now. Choosing yourself over a society that tells you to stay small and fragile.

I’ll take a little blip on the scale if it means I will be solid enough to hold the life I want for as long as I want it – no apologies needed.

Remember: A body that is hard to push around physically is harder to push around psychologically.

Lifting you higher than my overhead presses,

Mini Pause #110 | Longevity isn’t what you think.

Posted on February 21, 2026February 20, 2026 by stephanie-estima

Do you ever notice the difference in how men and women talk about longevity, especially online?

The bro model of longevity says: Optimize everything to extend your years. They ask, “How long can I live?”

The female model of longevity says: Fortify that castle so every single year feels great. We ask, “How well can I live?”

The difference matters.

WHAT

I don’t have any business living to 180, but I want to arrive at 80 feeling capable, don’t you?

And when I sit with that long enough, I notice something else underneath it.

Somewhere along the way, I stopped being afraid of aging. My fear became losing capacity – the slow erosion of independence, energy, and trust in my own body.

But when you scroll any biohacking bro corner of the internet, you’ll find longevity positioned like a competitive sport. Like time is something to be dominated.

*The following is said with a deep, gruff bro-voice with Hulk hands*

Optimize your cells.
Cold plunge at 5 AM. (Pass.)
Track HRV.

Inject peptides.
Build your 27-step morning routine that disregards all other people.
Pay 1 million dollars for a chance to be coached by me!

Longevity positioned like that is a performance. Aspirational immortality.

Women are less concerned about hacking biology and more about being a steward of it.

Experience – not extension. Better years – not more years.

💪 This is exactly what I do to build better years.

WHY

Women live about 7 years longer than men on average… but spend most of those extra years managing chronic conditions.

Researchers call this the male-female health-survival paradox: longer life, but often with less independence.

We watch and care for our mothers and grandmothers as they slowly lose mobility, strength, or trust in their own bodies. We love them through their long lives as they face joint pain, sarcopenia, osteopenia, metabolic disease, and cognitive changes.

So when we’re thinking about longevity, it’s not an immortality fantasy. We’re trying to prevent erosion.

THE REFRAME

When longevity is viewed through a female lens, priorities change.

Muscle becomes non-negotiable.

Yes, I’m all about celebrating the physical composition changes and your year-round peach season. I want that too.

But save some applause for the way skeletal muscle protects balance, metabolism, and independence.

The way bone density protects against fracture, strong connective tissue (joints, tendons, ligaments) literally holds you together, nervous system resilience tolerates wear and tear, metabolic flexibility protects energy and cognition.

✨Here’s my Metabolic Checklist to help you see where you’re at.

We’re not stacking supplements to cheat death. We’re strategically earning the capacity we need.

HOW

You don’t have to wake up at 4:30 AM to start the 27-step Dude Bro morning routine before anyone else needs you.

You need to be consistent (not perfect) with:

Progressive strength training

Enough protein (and then a little more)

Adequate calories

Daily movement

Sleep

Nervous system regulation

For women, longevity is the result of devotion. Showing up for your body every day, even when progress is quiet.

For Dark Roast Bettys ☕ like me who need to put some numbers behind those qualitatives, here are some age-based fitness performance targets you can aim for.

NOW

Decide what quality of life means to you, and chase it now. For me, it means:

I want to be strong enough to travel and put my own bag in the overhead compartment.

Steady enough to get off the floor after playing with my grandkids.
Pain-free enough to open my own dang pickle jars.
Beautiful enough in skin that still feels like mine.

Resilient enough to carry my own groceries.

Capable enough to remember my loved ones’ names and stories.

Confident enough to trust my biology.

Solid enough to feel at home in my body.

I’m not looking to defy or outsmart biology. I want to respect it and create the conditions my body needs to thrive.

So I’m curious…

When you eat, train, or make decisions about your health, are you training for immortality? Or autonomy?

In my experience, the women who feel strongest in midlife are the ones building bodies they can trust.

I’m in. Are you with me?

Mini Pause #109 | A Valentine’s Love Letter to my Grandmother

Posted on February 14, 2026February 13, 2026 by stephanie-estima

Valentine’s Day isn’t just about romantic love. It’s about inherited love and the devotion that a woman builds inside her own body.

We are taught to think of love as something that arrives from the outside.

A partner. A gesture. A bouquet. A moment. A white dress. A Disney prince coming to ‘save’ a princess.

But the deepest loves in a woman’s life are usually less grandiose and longer-lasting.

They look like stories told at a kitchen table. Observing other women care for themselves without apology.

They are learning, without being told, that your body is not something to shrink away from.

For me, this was my grandmother.

She loved herself and was unapologetic about it.

She would do her hair and put on a flowery dress and red lipstick just to walk to the mailbox.

She would go to the mall hours before the stores opened and would walk laps without crowds. For her, walking wasn’t a punishment. It was care.

She was my idol.

The way she would relentlessly take care of herself left a lasting imprint on me.

Looking back now, I can see clearly that when she walked for hours, she was aiding her metabolism, tending to her joints, improving her mood, and having time to socialize with her friends who joined her. (I used to love it when I could go with them because I would run ahead, and the whole mall was completely empty!)

She had a sewing room in her basement where she made all her own clothes. She would choose the fabrics herself and learned to create and drape clothes on her that honored her shape instead of fighting it.
When she told me stories (even if they were the same ones I had heard a hundred times), about her romance with my grandfather, how difficult it was when he was away during the war, and how much he had changed after he returned, she was teaching me that love evolves, but that her sense of self needed to remain strong.

She laid the groundwork for me to be who I am. I took her model for living and expanded it.

I took her walking and layered on muscle and conditioning.
I took her joint care and layered on connective tissue capacity.
I took her self-respect and layered on strength.

Same love language, slightly different expression.

I now view muscle not as something that has to be built through aggression, but built through devotion.

You show up.
You feed it.
You let it rest.
You respect seasons.

That is devotion.

Not the cinematic kind with extravagant gestures. But the kind that is durable.

It is doing the loving thing, even when you cannot immediately see the results.

The kind of devotion that holds your head up when life gets heavy.
The kind that stays when bodies change.
The kind that grows stronger because you invested early and consistently.

The kind that builds self-respect because you kept your promise to yourself.

When women train, we are practicing a form of love that isn’t conditional on being chosen from the outside, because really, what you are doing is choosing yourself. Even when (and especially when) you don’t feel like it, you're tired, and you have a million other things on your to-do list.

So today is Valentine’s Day, a day dedicated to love. My invitation to you is to zoom out and think about the kind of love you want to practice with the people in your life and with yourself.

Yes, romantic love matters.
But so does inherited love.

So does self-trust.
So does the relationship you’re building with the body that will carry you through the rest of your life.

Muscle is the proof of your devotion to yourself. By definition, then, it cannot be too masculine, too hard, too much, or too bulky. It is the expression of your self-respect and of your deservingness of love and devotion from yourself, for yourself.

We can honor love not just with flowers, but with stewardship.

We can honor our foremothers by continuing the devotion they modeled (however imperfect).

And in doing so, we can become someone the next generation will learn from, too.

Happy Valentine’s Day.

Mini Pause #108 | My boys get this. I didn’t.

Posted on February 7, 2026February 5, 2026 by stephanie-estima

This week, something clicked for me in a way I can’t unsee.

I was watching my teenage boys talking about their workouts. One is all about “curls for the girls,” and the other is working on perfecting his squat form… and I had this sudden gut punch of realization:

They are being encouraged to grow. They’re being taught to build, fuel, and take pride in watching their bodies change.

I got a pang of grief for little Steph, and all of my boys’ female peers who didn’t get this memo.

When I was their age, I was counting out nine almonds for a snack.

Measuring grapes.

Believing that smaller meant better.

That’s when it hit me: the fitness industry gave boys permission to expand and taught girls to disappear.

That conditioning didn’t stay in adolescence. It followed us into midlife, and most of us are still paying the price.

WHAT

When we were sixteen, we should have been chasing strength.

We should have learned what it feels like to push, to eat, to recover, to grow. But instead, we were told to stay small.

Boys were encouraged to celebrate and feel the JOY of their bodies responding to effort.

Girls got fear.

Women were robbed of the most formative training phase of life:

Learning what muscle feels like

Watching strength accumulate

Experiencing hunger as information, not moral failure

Building connective tissue and bone while hormones were supportive

So here we are, decades later, trying to build muscle and bone in our 40s and 50s… and maybe for the first time… without the hormonal runway we were meant to have at fifteen.

And then what do we hear?

“I don’t want to get bulky.”

That sentence didn’t come from biology. It came from a lifetime of conditioning.

That muscle growth is masculine. That tissue is dangerous. That strength wasn’t for women.

It makes me feel so many things. Sadness, anger… and a righteous desire to kick some ass at the gym.

Because strength training isn’t just about lifting weights. It’s about reclaiming something that was stolen from us: the right to take up space. That should have been ours all along.

Midlife strength is emotionally loaded for women because we missed out on the developmental milestone of celebrating our pride. Our appetites. The satisfaction of watching our bodies respond.

It’s radical to unlearn shrinking and trust growth. It feels foreign, but I promise you:

Muscle is not the enemy. It’s structure. It’s posture. It’s confidence you don’t have to perform.

HOW

This week on the podcast, I talked with Dr. Doug Lucas about what’s silently sabotaging women’s strength and bone health – and it’s not your hormones.

It’s the 1100-calorie trap.

So many women (and Dr. Lucas agrees… nearly 100% of his osteoporosis patients) are living in a chronic caloric deficit.

And here’s what that does:

When your intake is too low, your body can’t build.

You lose muscle. You lose bone. You lose resilience.

Your body stops prioritizing growth and shifts into survival mode.

The tragedy is that most women do this in the name of “health.”

They’re lifting, walking, doing the right things, but starving the very system they’re trying to strengthen.

In biological terms, you’ve tipped too far toward catabolism (breakdown) and never give yourself enough substrate for anabolism (building).

That balance between breaking down and rebuilding is where true longevity lives.

NOW

Your assignment is to start reclaiming your right to build – muscle, bone, confidence, energy.

Here’s where I’d start:

Eat enough to build. Food is raw material, not moral currency.

Lift progressively. Your bones, joints, tendons, ligaments, and posture depend on it. (If you need structure, LIFT will guide you step-by-step.)

Rest intentionally. Recovery is where adaptation happens.

Reject shrinking. Every time you nourish and train for strength, you’re rewriting the story the fitness world gave you.

We may have missed our teenage bulk, but it’s not too late to invest in the wisdom, purpose, and freedom to grow that midlife offers us.

Maybe we’re not teenagers anymore.

But we are Queenagers.

And the new rite of passage isn’t fitting in, but it’s filling out the life we want.

So tell me, Queen… are you ready to build something?

Mini Pause #107 | 9 Ways Your Cycle Affects Your Training 🩸

Posted on January 31, 2026January 30, 2026 by stephanie-estima

The internet is loud when you’re a woman who dares to age.

It’s loud when you’re a woman who dares to lift heavy and build muscle.

It’s loud when you unapologetically educate midlife women about their own bodies.

And on my feed, you know who’s making (most of) the noise?

Well, let’s just say it ain’t me.

These are random, unqualified [insert expletive here] sitting behind their keyboards telling me what a woman “should” look like at 45. At 55. At whatever age they deem judgable. (I may or may not have gone off in my stories this week about this very topic.)

It’s wild, Betty.

You can dedicate your whole life to studying, training, building businesses, raising a family, and kicking ass in every domain… and you’re still reduced to your appearance. That’s the culture we’re in.

It’s the same culture that doesn’t study women’s health and instead treats us like small men… or tells us to suck it up when some troll on Instagram comments on our bodies.

So today, I want to talk about something that’s getting wildly oversimplified on the fitness internet: women’s physiology.

WHAT

The EBITS (Evidence-Based Internet Trolls… both men and a surprising number of women) keep shouting that the research shows “no significant difference in muscle-building capacity across the menstrual cycle.”

As if women are single-variable experiments. As if they have any clinical experience.

And technically? They’re not wrong. But they’re missing the entire body for the muscle fibers.Yes, women can build muscle in every phase.

Yes, progressive overload still works.

Yes, mechanical tension still drives adaptation.

No, you’re not wasting half your month.

But if we’re only measuring muscle, we’re ignoring everything else that makes us human.

WHY

Performance isn’t just muscle. It’s about a dozen other systems that shift in rhythm with your hormones.

Here’s what DOES change across your cycle, and why it matters, and how your performance may change across the menstrual cycle:

Connective tissue: Estrogen fluctuates throughout the cycle and affects ligament laxity, tendon compliance, and joint stiffness. You’re still growing muscle, but the same lift can hit differently week to week, and that matters for injury risk.
Heat tolerance: Progesterone raises your core temperature during the luteal phase, making cardio feel harder at the same output. Ever wonder why indoor spin classes have fans all over the place? To decrease your perceived exertion and help you avoid overheating. If you’re getting tired earlier in the second half of your cycle, this might be why.
Fuel use: You’ll rely more on carbs at some points in your cycle, and more on fat at other points. This affects high-intensity repeat efforts, sprint tolerance, and fatigue when there is a fuel mismatch. Want bursts of energy and explosive power? You need carbs. High intensity? Call on your anaerobic system. If you’re not fueling well before training, you’re going to experience a lot of variation over your cycle.
Insulin sensitivity: The late luteal phase brings more blood sugar swings and lower insulin sensitivity. You might feel shaky mid-workout, tired earlier, or get ridiculously hangry post-workout. That reflects your increased recovery demands. You might need to take an extra day (gasp!) or two (!!) to recover. (You might need a deload week too, but I feel like I’m already pushing it by suggesting a day off!)
Coordination and balance: Your proprioception, timing, and motor unit firing efficiency change with hormone fluctuations – you’re not just clumsy. This might look like your lifts feeling “off” even if the strength is there, or your technique degrading earlier than expected. This is a good time to modify technical lifts because they require more cognitive effort to maintain form, aka protect from injury.
Breathing efficiency: Progesterone increases your respiratory drive, making conditioning feel harder even with the same VO₂. You’ll notice this most in metabolic conditioning finishers, interval work, circuit training, and even high-rep leg training. We’re more efficient breathers in the luteal phase. (Check out my convo with Patrick McKeown for a fascinating deep dive on this.)
Pain tolerance: Estrogen modulates your pain sensitivity and ligament and tendon behavior. Throughout the cycle, your path threshold will fluctuate, joint discomfort can feel more pronounced, and you might have puffy, inflamed days. This doesn’t necessarily mean injury, but the estrogen fluctuation does change tolerance and movement confidence.
Sleep and recovery: Hormonal changes affect REM depth, sleep continuity, and overnight recovery signaling, which explains why two identical sessions can feel wildly different. Heart rate variability dips without an obvious cause (mine always tanks after I ovulate up until I bleed), and motivation drops even when discipline is high.
Fluid balance: Hormones influence how your body handles sodium, water retention, and tissue pressure. This impacts joint stiffness, puffiness, heavy limb sensations, joint compression tolerance, and range of motion. Your tissues may be fine… they’re just holding more volume.

So yes, you can (and should) train hard all month, but what “hard” looks like also changes from the follicular to the luteal phase, and pretending nothing changes in your body is just bad science. Things change, so any trained clinician would tell you that adaptations should be made.

Elite performance has always respected system-level shifts… because men have them too. Women just have fluctuations that can be mapped into a calendar.

HOW

This is where I bring in the Big Ovary Energy.

I’m not interested in “hacking” my cycle or “overcoming” my hormones. I’m interested in working with them.

Here’s what that looks like in real life:

During my follicular phase, I go heavier. I can go all out and still recover faster, sleep better, and push intensity. Here is where I typically push for PRs

In the luteal phase, I pivot. Shorter rest periods, lighter weights but higher reps, more tempo work, more walks, more recovery tools, and more social media and email rants to you.

In the context of muscle building (which yes is important but it is not the ONLY thing), I am always aiming to approach muscle failure, understanding that the load and intensity with which I will reach it will change.

I stay consistent, but I stop expecting myself to feel the same every day.

I track my cycle and my energy. If my lifts feel off because my joints or tendons feel a bit tweaky, I adjust the volume or technique to prevent injury. I don’t label myself as lazy.

This is what women’s performance looks like when you respect your biology. Adaptive, intelligent, dynamic, and still powerful as hell.

NOW

If your workouts have felt “off,” I want to invite you to see it as feedback rather than a weakness.

Note when your energy, sleep, and strength fluctuate this month.

Give yourself permission to adapt rather than push.

Remember that building muscle isn’t the whole story. Building awareness is key.

I’m tired of people pretending that women’s bodies are hormoneless and unchanging.

Last week, I laid out 6 New Rules of Femininity, and I might add this to the list: train with enough intelligence to handle a dynamic system and still dominate.

Go out there and lift something heavy, no matter where you’re at in your cycle.

Mini Pause #87: The #1 Way Lifting Heavy Can Cause Injury (and How to Avoid It)

Posted on September 13, 2025 by stephanie-estima

Muscle sure is having her moment on social media, isn't she!

“Lift heavy, ladies!”
“Be a Muscle Mommy!”
“Build that booty!”

The cheerleading is loud, and I'm not going to pretend it isn't motivating, but something gets lost in the noise:

Strength isn't just about muscle.

When you pick up a weight, whether its a 10-pound dumbbell or a heft of racked plates, your muscles are not alone in carrying the load. Ligaments and tendons are their sisters. Articular cartilage is their cousin. They're all in this together, and they all adapt and recover on their own clocks.

If your training program only takes into account the recovery timeline of muscle, you're most likely going to outpace your connective tissue capacity.

What does this look like? The weakest links tend to complain first. Think of morning tendon stiffness, joint aches, and ligament strains.

Remember that British game show The Weakest Link?

Bad programming is like looking right at your tendons with a sassy British accent and saying, “You are the weakest link. Goodbye!”

So, this is my love letter (my soliloquy, if you will) to the entire network of tissues that keep you strong. Because if we want lasting gainzzzz (yes, with all the zs, like the gym bros say), we have to honor the whole system, not just the muscles in the mirror.

WHY

We have a variety of tissue tolerances to consider when lifting weights to help us go heavy and avoid injury.

Tissue tolerance is a tissue's capacity to absorb, transmit, and recover from load without breaking down. And here's the truth: your tissues don't give a flying F about the number on the weight. They don't see “15 pounds” or “2 plates.” They only know load, mechanical tension, acute damage, and maximum recoverable volume.

So let's look at the recovery timeline for each tissue:

Muscle

Muscle is quick to adapt. Neural gains show up in weeks. Visible hypertrophy (muscle growth) in 6-8 weeks. With rich blood flow and fast protein turnover, she thrives on regular work. Think 2-4 sessions per week for each muscle group. Nature

Tendons

These are slow alchemists. They remodel collagen at a glacial pace. If you've ever injured a tendon, you know it takes a lifetime. Think months, not days. PMCSpringerOpen

With a sparse blood supply and collagen that can be decades old, their improvements come only with steady, patient loading. PMC

Tendons love the “low and slow” approach and punish sudden spikes in effort. True changes in tendon stiffness take at least 12 weeks. SpringerOpen

Ligaments

Ligaments are the baddies that stabilize joints, and they're similar to tendons: dense collagen, slower metabolism, and slower to respond.

Think of ligaments like the introverts at the party. She wants to be there, but she takes a little longer to warm up and get comfy. (Hi, it's me!) PubMed+1

To strengthen a ligament, you want multidirectional movement: jumping, decelerating, sudden changes in direction. These movements sharpen neuromuscular control and protect your joints. ASME Digital Collection

Side Note: I would LOVE to go on a nerd safari on ligaments in a future newsletter. I'm game if you are.

Articular Cartilage

Articular cartilage is the plush cushion between your bones. She's there so your bones don't rub together, because wow that's not nice.

Unlike other tissues I've mentioned, articular cartilage has no direct blood supply of its own and minimal collagen turnover and renewal. PubMed

The only way to keep joint cartilage healthy is through consistent loading. She loves regular, moderate, and cyclic compressions, like walking, cycling, and most steady-state cardio machines. Sedentary is her downfall. PMC

HOW

Okay, Betty, it's time for you to honor all your tissues so they rise together, strong and resilient:

(Want a quick and easy program build to match each tissue's healing clock? LIFT is for you.)

1. Sequence Your Week
Muscle strength sessions can happen often (2-4 times per week per muscle group). Tendon- and ligament-heavy work (slow lifts, plyometrics, change-of-direction) need at least 48-72 hours of rest between exposures.

2. Master Form Before Load
In LIFT, our Master Form videos help you own the movement before you ever load it. Good form isn't just about looking impressive. It's how you protect your tissues and respect their tolerance.

3. Watch for the Signals
Green (Go!): Mild muscle soreness, tendons that warm up and feel fine by the next morning, and joints that feel “used” but not puffy.

Yellow (Yield): Morning tendon stiffness for more than 24 hours, lingering joint aches, or from breaking down under fatigue.

Red (Stop and Deload): Swollen or locking joints, sharp instability, night pain, tendon pain that worsens as you warm up are all signs to rest and see a professional.

NOW

Here's what you can expect when you play the long game:

Muscle: You'll feel fitter within 2-3 weeks with visible changes in 6-8.
Tendons and Ligaments: Real, durable change happens over 8-16+ weeks, with tendon stiffness improving best at >12 weeks.
Cartilage: Healthy cartilage loves consistency. Regular walking and rhythmic, cyclical movement keep it nourished and thriving.

Think of your body like a financial portfolio. You wouldn't put all your money in one stock and hope for the best. In the same way, your tissues thrive with a diverse portfolio of movements. Strength, cardio, recovery, and multidirectional play… it all matters.

So yes, lift heavy, Betty. Build muscle. But train like the queen you are: with wisdom, patience, and respect for the whole kingdom (or queendom) of tissues that carry you forward.

WHAT I LOVE THIS WEEK

BIOptimizers

You can nail your diet and workouts, but if your sleep is suffering, your results will stall.

A compelling study recently found that poor sleep slashed fat loss by 55% and increased muscle loss by 60%, even when calories stayed the same.

Think about these two women on the same plan. The rested one loses fat and keeps muscle while the sleep-deprived one loses the muscle she worked so hard to build (while living exhausted!).

Here's why: Poor sleep spikes hunger hormones, slows fat burning, and makes your body more likely to store fat.

That's why you need Magnesium Breakthrough from BIOptimizers. It combines all 7 essential form of magnesium to help you fall asleep faster, sleep deeper, and wake up calm, clear, and ready to kick butt.

Try Magnesium Breakthrough and use code ESTIMA for 15% off.¹

Apollo

When stress, anxiety, or poor sleep creep in, my go-to is Apollo Neuro. It's a wearable device that feels like cheating on a test for your nervous system.

Apollo uses gentle, rhythmic vibrations (vibroacoustic stimulation, for the nerds among us) to activate your parasympathetic nervous system, which is your body's natural calm mode.

The results are powerful. It helps boost heart rate variability (your body's stress-resilience score), lowers cortisol, and supports the release of serotonin and dopamine (your feel-good neurotransmitters).

Translation? You feel calmer, sleep more deeply, and bounce back from stress with strength.

The best part is it's risk-free to try with a 30-day guarantee. Strap it to your wrist, ankle, or clip it to your shirt and let Apollo guide your body back into calm.

Try Apollo Neuro now and get $60 off with code BETTER.²

Create

I used to think creatine was just for gym bros, but after 40, the rules change. We lose muscle mass faster, recovery slows, and even our mental sharpness can feel inconsistent.

Creatine directly addresses all of this, and the research for women is nothing short of incredible.

That's why I love Create's creatine gummies.

No messy powders, no chalky taste, and no “forgetting” because it's unpleasant.

These taste good and they're portable. I just throw them in my purse and I never miss a day.

Since making them part of my routine, I've noticed better strength in my workouts, faster recovery between sessions, and, honestly, clearer thinking and steadier energy throughout the day.

If you want to maintain muscle, brain power, and energy as you age, creatine isn't optional. It's foundational.

Try Create here and use code DRSTEPHANIE for 20% off.³
