With a dozen obstacles to test your mettle, this worldwide series of 5K races is like circuit training on steroids—expect to scale 12-foot walls, crawl under barbed wire, and jump over fire. You don't have to train for the Warrior Dash (runners and walkers of all fitness levels are welcome), but select Anytime Fitness gyms nationwide now offer Warrior29 classes to prepare you.

Consider this a far more exhilarating way to improve your endurance, upper-body strength, and agility. And the end-of-course party with live music and beer is the perfect way to celebrate crossing the finish line.
