American Muscle

The methods that strength coach Mike Barwis uses in his Detroit gym may be unorthodox -- some might call them crazy -- but the results his clients achieve are undeniable. That's why Barwis could be assisting a well-known athlete like NFL star Richard Sherman one day, and the next he's helping a regular Joe just getting into fitness. "American Muscle" profiles Barwis and the varied clients who travel to Detroit to work with him and his staff. For more than a decade, he served as head strength and conditioning coach at West Virginia University and the University of Michigan, and he has trained more than 500 Olympic and professional athletes in 40-plus sports.
