7. Sweat Inc. (SPIKE)
On Sweat Inc., it isn’t just about finding out who the fittest contestant is, it’s about finding out who has the best idea for the next big workout craze. Consider it a Shark Tank for fitness concepts, of sorts, that’s looking for the next Tae Bo or Broga. Jillian Michaels hosts and judges alongside TRX creator Randy Hetrick and Obi Obadike, a trainer and former Division 1 collegiate athlete. The workouts are tough — they have to be able to impress the judges — but the contestants also need a solid business plan to win. As a result, the focus isn’t always on working up a sweat, but it's a neat look into fitness entrepreneurship.
