About this episode

Join leading experts in female physiology, performance, and longevity, Dr Stacy Sims, Dr Vonda Wright, Dr Mary Claire Haver, and Dr Natalie Crawford, in a two-part roundtable on women’s health. In today’s moment, they unpack the exercise advice women are rarely given, from why more running is not always better, to how under-recovery, hormones, stress, and menopause can completely change what the body needs. They reveal why the right kind of intensity could be crucial for strength, body composition, and even brain health, and why many women may be training harder without getting healthier. This Moment is from Part 2 of a 2-Part Women’s Health Series. Listen to the series here!

Episode summary

I keep hearing VO2 max is the holy grail, so should we all chase a big number by cranking cardio hard?

VO2 max improves with brief, uncomfortable efforts, not endless grind. Think four-minute pushes with equal recovery, for four rounds, and do that at most once a week.

My go-to is thirty seconds all-out, then two to three minutes of true rest, for four repeats after a warm-up. Any machine works because it’s a heart-rate play, not an equipment one.

Running clubs are booming, and people are swapping lifting for miles. Should we be worried?

Running only is lopsided. About fifty-eight percent of frequent female runners show a short luteal phase from low energy availability, which is a sign the brain is sensing a deficit. Keep three strength days and slot runs around them for a healthier balance.

Getting strong through full range boosts running economy and reduces injury. Daily shuffles build the strong muscles stronger and the weak ones weaker, which is how people end up in my clinic.

Everyone’s chasing marathons, and some friends look rail-thin. Is that actually healthy?

Some are built for distance, but many lean endurance athletes—especially women—carry more visceral fat than you’d guess due to inflammation, underfueling, and suppressed estradiol. DEXA often reveals it even when the mirror doesn’t.

Give me the evolutionary take. What would our bodies have done long ago?

In scarcity, women’s cycles pause and fat is conserved because reproduction would be risky, while men tend to get lean and hyper-focused to find food. Layer today’s constant stress on top, and cortisol drives more fat storage.

Ancient stress hit in bursts, like a predator chase. That surge ended once you ran. Now the same hormone surge happens for a tense meeting and then just lingers.

Your body frees glucose so you can bolt, but modern stress doesn’t end in a sprint. You sit in it, and the chemistry never clears.

Big picture, most people still don’t move enough. I’ll take anything that gets you off the couch today, even ten air squats.

Your listeners skew motivated, but I see many fit women slide into hypothalamic dysfunction from underfueling and overdoing it long before periods fully stop. In men, true brain-driven low testosterone is rare compared to outside factors.

I call it under-recovering. Fuel, sleep, and recovery framing helps people actually fix it.

What about the loud online voices telling women it’s just willpower?

That’s harmful. You’re not broken; the system is stacked. Let’s use tools that move you one doable step at a time.

Do exercise rules change in perimenopause?

You want potent stress with equal recovery. Heavy lifting creates micro-damage that signals stronger repair, and true sprints trigger changes that pull glucose into muscle and signal less visceral fat. Live in the middle and you keep cortisol humming, which is the opposite of what you want now.

So shorter, harder sessions that spark adaptation, without marinating in stress?

Yes—plus real low-intensity work for blood flow and recovery. For most, avoid the mushy middle unless you’re training for endurance; touch the top end briefly, then drop to easy.

In a week, lift heavy two to four days with one big compound move, then add jumps or balance. Keep other days easy movement, sprinkle in a couple sprint sessions, and layer habits slowly before adding a VO2 day.

Foundations first: sleep is non-negotiable for body comp and stress resilience. Then dial nutrition and activity in whichever order you’ll actually do, and don’t skip community and nature for your parasympathetic health.

Late-life success tracks with community and active minds. Keep using your brain and staying connected if you want a great final decade.

Postmenopause, does the plan change?

Start early if you can, but it’s never too late. Progress carefully and build support around each modality.

I’m postmenopausal and do all of it. Heavy is relative, and good form rules.

Find your one-rep max safely, then work at roughly seventy to eighty percent for about five solid reps; that’s heavy. My first clean single was around twenty pounds, and I built from there.

Women often undershoot their strength. Ditch the forever ten-pound dumbbells and choose weights that challenge you instead of chasing ‘tone’ with endless reps.

Train for strength now, then play with tempo and power to hold onto those fast-twitch fibers as you age.

We relate better to near-term wins. Studies show many people treat their future self like a stranger, which is why pitching cognitive and performance gains lands better than distant benefits.

Many women are caretaking parents while raising kids and working, and it’s brutal. Caregivers of a parent with dementia face about a sixty percent higher mortality risk, likely from stress—we don’t want to pass that burden to our daughters.

Brain health is another reason to sprint. Women have fewer glycolytic fibers and lose them with age, so producing lactate with high intensity feeds the heart and brain and may help prevent metabolic missteps tied to dementia. Men often benefit more from extra easy work for fat burning.

Brain glucose use shifts wildly across peri to postmenopause, and the patterns may flag who’s on a dementia trajectory.

Older cohorts of women had fewer chances for cognitively demanding careers, which likely affected neuroplasticity and dementia rates. Today’s mental stimulation helps, but the stress load is still real.

Think of neuroplasticity like building bone, but in your brain. You’re laying resilient pathways, and that takes an active plan, not wishful thinking at ninety.

We’re reading less and scrolling more, especially before bed. Story-rich reading builds the brain in ways a phone’s dopamine hits don’t.
