HOW: Grab a long towel and get into the split stance position with your inside leg forward and your knee slightly bent. The outside leg is back with your toes pushing into the ground just to help with balance. While holding the towel with both hands, pull it up overhead from one side and slam it down on the other side. Repeat on the opposite side for the prescribed reps.
FEEL: You should feel your core and arm muscles working as you slam the towel to each side. You should also feel your glutes, quadriceps, and hamstrings working to maintain the split stance position.
COMPENSATION: Don’t move your legs, keep them centered the whole time.
