Our guest today is Paul Francis. When Francis read about NASA's problem with astronauts exercising in space, he contacted the agency about a technology he had developed using resistance instead of weights. He later licensed that SpiraFlex technology to Nautilus, and they used it to develop the Bowflex Revolution home gym. Francis came up with a way to miniaturize the components and launch OYO Fitness, which offers the DoubleFlex Portable Gym and a follow-up product called DoubleFlex Black. Listen in to Francis' path from inventor to business owner.
