On episode 14 of The Speed Podcast, coach Breitenstein spoke with Frank Duffy, a trainer at Cressey Sports Performance and co-owner of Par Four Performance. One of the things that we were really interested in discussing was Kinstretch: a system that is born out of scientific research. All of the movements and training techniques have been selected based on a meticulous and rigorous investigation of evidence, conducted by physical conditioning and medical experts, as it pertains to body control, injury prevention, joint health, and physical longevity. This is a great episode with a lot of great insight.
