Go behind the scenes of a Spartan race with Fitness On Fire   In a special bonus episode of the Escape Your Limits, the power couple, obstacle race specialists and co-founders of Fitness On Fire, Josh and Haydee Graves, take host Matthew Januszek behind the scenes of their California community fitness venture.   With a huge level of energy from people cheering you on or pushing through their limits to reach the same finish line as you, sometimes literally, Fitness On Fire is more than just a gym. Join us on the tour.
