In this episode of the Keiser Human Performance Podcast, Gabe Derman sits down with legendary performance coach Randy Huntington, whose coaching career spans more than four decades and includes work with world record holders and Olympic medalists such as Willie Banks, Mike Powell, and Su Bingtian. Randy shares the lessons he's learned coaching some of the fastest and most powerful athletes in history and explains why the calf complex has become one of the most important—and often overlooked—areas in performance training.

The conversation explores the role of the ankle and plantarflexors in speed, acceleration, and force production, and how Randy's understanding of lower-leg function evolved throughout his career. He also discusses his first experiences with the Keiser Seated Calf Press, what makes pneumatic resistance unique, and how the machine became an important part of his training system with elite athletes.

From improving stiffness, power, and acceleration to enhancing performance across multiple sports, Randy explains how targeted calf training can influence athletic outcomes. The episode wraps up with a discussion on Achilles injuries and the impact of surfaces and footwear.
