In an episode of Power Athlete Radio, I sat down with Dr. Bryan Jasker, a leading sports scientist, to break down the real story behind lactic acid, or more accurately, lactate. And why it’s a game-changer for tracking performance and metabolic health. Most people still think lactate is just what causes muscle soreness and fatigue. It’s not. Lactate is actually a key fuel source and a powerful signal that helps your muscles work and recover under pressure.

On an episode of Power Athlete Radio, I had a great conversation with Antonio Squillante, Head of Sport Performance and Training for USA Cycling’s Sprint Program, about something a lot of coaches miss -  the theory of “priming the pump” in young athletes. This concept comes from the work of Carmelo Bosco, the legendary Italian sports scientist who worked with the national track and field team.

On Power Athlete Radio, I caught up with Antonio Squillante, Head of Sport Performance and Training for USA Cycling’s National Track Sprint Program. We dug into the science behind hypertrophy and how strength adaptations differ between men and women. With a PhD in Biokinesiology and a decade of hands-on coaching experience, Antonio brings a much needed mix of deep research knowledge and practical insights on how this applies to elite and recreational athletes.

When it comes to training high-level sprinters, there’s always this ongoing debate: How strong is strong enough? Clint Martin, UT Track’s Strength Coach, tackled this head-on during his chat on Power Athlete Radio. His take is that strength is absolutely crucial — but it’s just one piece of a much bigger puzzle. To really unlock an athlete’s top-end performance and keep them healthy, you have to balance strength, speed, power, and flexibility. Dialing in that balance is where the real magic happens.

Recently on Power Athlete Radio, I had an enlightening conversation with Dr. Craig Heller from Stanford, where we got deep into the science behind cooling mitts and how they can impact athletic performance. Cooling seems simple, but it turns out it has some wild effects on central nervous system efficiency and recovery, and there’s some crazy overlap with things guys like Louie Simmons were talking about years ago.
