HOW: Start in a standing position balancing on one leg with your hands holding onto a sturdy surface/object to help with balance. Perform a skater squat by bending your hip and your knee letting your knee go forward, however also let your upper body lean forward by hinging at your hip. Return to starting position, repeat, perform on both sides.
FEEL: You should feel all the muscles in your leg working, especially your glutes and your quadriceps. You may feel your core working as well to maintain torso position.
COMPENSATION: Do not lose balance, try to keep your knee tracking on your foot, do not let your knee cave in/out. Do not let your pelvis sag on the other side. Do not over-rely on upper body support.
