Randy Hetrick is the creator of the TRX Suspension Trainer and the founder of TRX. Inventing a workout while operating in a war zone probably makes Hetrick's story one of the most interesting the fitness industry has ever known. But it's what he has done afterward that is just as incredible. In this episode of "Gym Class: Heroes of Fitness," Hetrick, a former Navy Seal, joins Hossein and Leigh to tell the start-up stories that have led to one of the most innovative new products to hit the fitness industry in years.
