Brian Kretsch, trainer and manager at traversefit is one of only two ninjas to compete in every season of American Ninja Warrior. Ninja Warrior training has evolved into its own specialized form of training, which draws on a variety of physical disciplines. We're ecstatic to say it's found its way onto Vagaro. Listen as we talk with Brian about the benefits of Ninja training, how the sport has evolved, the challenges of running a Ninja Warrior gym, and Traverse’s plans for the future. #ninja #americanninja #americanninjawarrior #traverse #briankretsch #warrior #warriortraining #ninjatraining
