Jon Messner and his guests have conversation about exercise, science, and food. ---- Jon Messner was in a car accident when he was 17 and knee surgery seemed inevitable. Jon wanted to avoid surgery and started reading physical therapy, functional anatomy, and sports medicine books. Jon discovered knee pain may be the result of weak muscles, but was reluctant to accept that his knee pain wasn’t caused by the car accident. Despite his misgivings, Jon started lifting weights and strength training, and his knee pain disappeared in two months. Jon opened Messner Strength Training in 2011 and shortly after, started coaching college track and field. Jon’s unique approach have resulted in numerous school records, personal bests, and conference championships.
