HOW: Stand with a wall in front of you. Place your hands on the wall about shoulder height and slightly lean into it. Begin with your feet together. Shift your weight to one side as you kick one leg out straight behind you and back to the starting position. Repeat on the other side for the prescribed amount of reps.
FEEL: You should feel your hip muscles working.
COMPENSATION: Don’t lean too far forward. Kick your leg straight to the back, not sideways or forwards.
