If you don't already know who UFC Welterweight Champion, George St-Pierre is, you soon will. He goes by the nickname GSP and he's poised to become MMA's first true crossover star, but only if he wins his next fight against UFC Lightweight Champion, BJ Penn in UFC 94. Penn is moving up a weight class in his quest to be the first UFC fighter to hold two championship belts at the same time.
GSP is recognized as one of the best conditioned fighters in one of the most demanding sports in the world. And the TRX is a fundamental element of his strength and core training program. In this month's issue of Men's Fitness, GSP's trainer Jonathan Chaimberg, shares the core workout that George uses to build and maintain his powerful, rock-solid core. Check out GSP's core workout featuring the TRX.
