Is It Perimenopause? What to Know Before You Start MHT
Menopause hormone therapy (MHT) is one of the topics Iām asked about most, and the conversation around it has changed dramatically over the years. For two decades after the 2002 Womenās Health Initiative (WHI) study, women were told hormones were dangerous (which was largely a fault of media mi...

Holding It All Together
Iāll be honest: more than once this week Iāve woken up and itās taken me a moment to work out which city Iām in.
Highlights of the last few weeks include speaking at The Epicenter in Portland, Oregon, for the Womenās Global Sports Summit; a quick trip across the Pond for the Wellness Oasis in L...

Puberty Isnāt A Plateau, Itās a Rebuild
Think back to when you were 12 or 13. Did you get slower? Clumsier? Was there a season where you stopped enjoying sport and nobody could tell you why? For most of us, that dip was never explained. We were told weād lost interest, or that we needed to try harder; some of us quit entirely.
It too...

You Didn't Lose Fitness, You Lost Fuel
If you grew up in the ā80s and ā90s, you were handed two contradictory rulebooks. First, fat was the enemy. Then, almost overnight, fat was fine and carbohydrate was the problem. Neither was built on good science, and neither was built with active women in mind, yet both stuck.
I see the impact...

What My Grandmothers Taught Me About Aging Well
My great-grandmother lived to 105. One of my grandmothers made it to 106. The other was 97 when she died.
While the numbers on their own donāt tell you much, I can tell you what it actually looked like. All three lived independently. All three had their facultiesāsharp, opinionated, entirely th...

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. Iād 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, ...

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 āhealthy but declinedā state, and neither living longer nor avoiding illnes...

How Well Will You Age?
You might have noticed thereās 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 isnāt the same as better. And here's the thing nobody's telling you:Ā women already...

Where Do I Start? A Roadmap for Active Women Who Want to Get It Right
If there's one question I hear more than any other right now from active women, it's this: where do I even begin?
Thereās no doubt you're motivated and youāre asking all the right questions: you know that training, nutrition, sleep, and stress all matter, but the sheer volume of information out...

Why Jet Lag Hits Women Harder
I landed back in New Zealand last week after a month in the US and itās 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 ...

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...
