If you're an athlete on Mounjaro (tirzepatide), Ozempic (semaglutide), or any GLP-1 medication — or just curious what these drugs mean for training, strength, and sport — this episode is for you.

As a triathlete, coach, and someone who’s trained on a GLP-1, I’m breaking down what I’ve seen, what the research says (so far), and what coaches aren’t talking about.

The gender gap in GLP-1 studies — and why active women must lead their own data.
