Obstacle-course races can be a serious challenge. But perhaps even more difficult is trying to train for them. Grit Obstacle Training eases some of that pain by offering an indoor facility designed especially for obstacle racers. The gym layout includes ramps, stairs, and platforms, along with free weights, to build strength and stamina. And whether they are preparing for their next mud run or just looking to recapture a bit of youthful vigor, Grit Obstacle Training's schedule of classes can help further develop warriors-, Spartans-, and ninjas-in-training.
