Coffee, Decoded: What the Research Actually Says About Caffeine and Women

I'll say it upfront: I love my coffee. My mornings typically start with a strong cup, and many of the active women I know have a similar habit. So it's worth asking a question that doesn't get asked enough: how do we actually know caffeine affects us the way we think it does when most of the re...

Exercise and Aging: What Active Women Need to Know

In my previous newsletter, I examined three terms that reshape how active women should think about aging: longevity, healthspan, and peakspan. The takeaway was this: most of us spend the majority of our adult lives in a “healthy but declined” state, and neither living longer nor avoiding illnes...

How Well Will You Age?

You might have noticed there’s a word you can't escape right now: longevity. Everywhere you turn there seems to be supplements, podcasts, and biohacking protocols all promising to help you live longer. But longer isn’t the same as better. And here's the thing nobody's telling you: women already...

Far From Home, Close to the Work

I left New Zealand on April 12 with a carry-on bag, a full schedule, and the kind of quiet resolve that kicks in when you know you're heading towards work that matters. Two and a half weeks in, I'm somewhere between San Francisco and Los Angeles with a double espresso in hand, a voice that's ta...

Protect Your Brain for the Long Game

We spend a lot of time talking about muscle, metabolism, and performance, but not nearly enough time talking about the brain. Yet women are disproportionately affected by cognitive decline and Alzheimer’s disease. Alzheimer’s is a brain condition that slowly damages memory, thinking, learning, ...

Closing the Women’s Health Gap

For a long time—going back to my postdoc days—I’ve experienced firsthand how far women’s health and fitness research lags behind the male-focused default data. It’s become my life’s mission to help fix this, so today I’m extremely proud to announce a new research funding partnership that will h...

Menopause Changes Your Gut—Here’s Why It Matters

Most conversations about menopause focus on hormones. But there’s another system quietly shifting at the same time: your gut microbiome. The trillions of bacteria living in your gut influence everything from metabolism to immune function to brain health. And during perimenopause and menopause, ...

How Plants and Protein Can Help You Through Menopause

Most active women underestimate their daily protein needs—and the consequences become more pronounced in perimenopause and menopause. The current RDA for protein was established to prevent deficiency in sedentary people, not to help active women optimize their training and recovery—or to thrive...

Women Live Longer, So Why Aren’t We Aging Better?

Women live longer than men. On paper, we “win” longevity. But here’s the uncomfortable truth: many women are living longer, but those years are impacted by cognitive decline, cardiovascular disease, frailty, and loss of independence, especially after menopause. The real question becomes less ab...

Why the Female Heart Responds Differently to Exercise

Note: This is an anatomical and physiological review, not medical advice. Anyone with concerns should see their healthcare provider. When you train consistently—whether it’s endurance training, speed work, or strength—your heart adapts. That adaptation, which is often referred to as “athlete’s ...

Why Active Women Need Creatine

There are very few supplements I recommend across the board. Creatine is one of them. For decades, creatine has been misunderstood as something only bodybuilders or elite male athletes use. That misconception has kept many women from one of the most well-researched, effective, and female-rele...

Talking Menopause with Mel Robbins

My latest conversation with Mel Robbins drops today, and it touches on many of the questions I’ve been thinking about as we head into 2026: how women can support metabolism, build muscle, and work with their hormones as they train, recover, and age in a landscape that’s often noisy, trend-drive...
