James doesn't look like the "typical" runner - he's 6'6" and 250 pounds. A former professional rugby player, James has a degree in Sport Rehabilitation and is fully insured member of the British Association of Sport Rehabilitators and Trainers (BASRaT). He's the founder of Kinetic-Revolution and has an ongoing fascination with the functional biomechanics of running (in other words, how you move while running). In this far-reaching discussion, we talk about quite a few issues: Should overweight runners be more worried about injury? Is gaining weight more important for injury risk than being consistently overweight? Does training for weight loss differ than training for a race? How? Enjoy my conversation with James (and don't miss the announcement at the end of the show!).
