Dr Stacy Sims knows more about women's fitness than pretty much anyone we've ever spoken to.

She's the exercise expert who went viral for her breakfast routine, but that's just the beginning. Dr Sims is an exercise physiologist and nutritional scientist who's become the go-to authority for grown-up women navigating fitness in 2025.

In this conversation, Stacey shares why so much mainstream fitness advice is complete bullshit for women. She explains how ice baths, fasting, and soul-crushing cardio weren't designed for female bodies, and why "shrinking and pinking" men's advice doesn't serve us.

You're going to hear about the surprising differences between male and female physiology, why women aren't just "small men" when it comes to health, and what we actually need to feel vibrant and strong. Plus, yes, she'll reveal that famous breakfast that caught the internet's attention.
