Sit on the edge of the chair with your back straight. Pull your belly button in to engage your ab muscles and protect your back muscles. With your knee bent, lift one leg up slightly and hold for a few seconds. Then do 50-100 small pulses. Make this movement from your hip. (Pretend like your leg is a lever making your knee go up.) Don’t let your leg drop below parallel. Repeat on the other side. This exercise is great for strengthening your leg muscles!
