Texas native Adrian Peterson has been preparing for the upcoming NFL season at his own massive health club in Houston, which just opened in March. Peterson is the co-owner of O Athletik, a 35,000-square-foot gym that features an indoor soccer field and batting cages, an MMA training area, and a very intimidating inclined running hill.

Peterson gym already has more than 1,000 members, and he says he plans to keep training there personally during his offseasons.


"We're not making it a training facility; not promoting it and trying to get athletes to come train here. We're trying to get people that are into MMA, want to learn how to box. You can do your basic workouts, like you do at 24-Hour Fitness."
