How to Think Like an Athlete

I was giving a keynote earlier this year to a room full of active women, and asked them to raise their hand if they considered themselves an athlete. I’d say maybe less than a quarter of hands went up. The rest looked around, unsure. The scientist in me had been curious about this for a while, ...

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...

Why Jet Lag Hits Women Harder

I landed back in New Zealand last week after a month in the US and it’s wonderful to be home, to be back with my family, and to be catching up on sleep. Well, almost. While my body is physically here, my body clock is still somewhere over the Pacific. Jet lag is one of those things that sneaks ...

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 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...

Why HIIT Matters for Women’s Body and Brain Health

If you’ve been following me for a while, you know I love busting myths—especially in women’s training. One of the most persistent? “More long, steady cardio is always better.” Don’t get me wrong—Zone 2 training has its place. It builds your aerobic base, supports mitochondrial health, and imp...
