WHY This works the legs and glutes, and the towel provides support to let you move in to your split squat with the correct technique. HOW Partner A, stand tall with your feet shoulder-width apart and abs engaged. Grasp the doubled-over towel in both hands and extend your arms, keeping your shoulders down and your chest up. Partner B, stand tall with feet shoulderwidth apart and grasp the towel with your right hand (as partner A pulls to create resistance). Take a big step back with your right foot and lower your body until your front thigh is parallel to the ground and your back knee is bent and nearly touching the floor. This is 1 rep.
