"Dad taught me everything I know. Unfortunately, he didn’t teach me everything he knows."  -Al Unser. This week on GymClass we interview Michael Martin, a CSCS, owner of Impact Physical Therapy, certified orthotic fitter, athletic trainer and exercise physiologist as well as my dad. We pick his brain on the differences between rehabilitation for his PT patients versus recovery for athletes he's trained, bug him with nagging injury questions and have a worth it or B.S. segment on different recovery devices and equipment.
