HOW: Place your back against a wall and shuffle your feet out. You can start with your feet in a staggered position or assume this position once you’re in your wall sit. Drop to 90º at your knees and hold for the prescribed time.
FEEL: You will feel the quad of the leg closer to the wall worker harder than the opposite side.
COMPENSATION: Avoiding hinging forward through the trunk and losing contact with the wall. Keep your knee in line with your foot without caving it in.
