At the aptly named Warrior Fitness, two former Marines (Alex Fell and Ruben Belliard) order you through a Marine Corps–style obstacle course—scaling walls, climbing ropes, blister-inducing monkey bars. Each session includes lunges, push-ups, hurdles, and jumpsquats, plus Rocky-style sprints up multiple flights of stairs. A good portion of the drills are done with a partner. Fell and Belliard say that teamwork is part of the learning experience—or maybe they know you need support to make it to the end.
