The Science Behind Getting Fitter, Faster & More Efficient | Reece Barclay | Ep 56

In this episode, we dive deep into the science and practice of endurance performance — from starting sport at a young age and discovering swimming at 13, to VO2 max, efficiency, training intensity, nutrition, hydration and heat adaptation.

We also explore why working harder isn't always the answer, how to structure training effectively, and the key principles athletes can use to improve performance without simply adding more hours.
