The chain of core muscles may be complex, but strengthening them doesn’t have to be. This trunk-focused routine, created by Equinox coach Michael Ryan, covers essential functional movements—push, pull, squat, hinge, and walk—in just six exercises that keep your entire torso engaged. The beauty? Do it right and you’ll build every muscle in your body. The bonus: You’ll need only one kettlebell.
