1. Basic Leg Lift
Lie on your right side with your legs outstretched, feet flexed, and right elbow bent so the right hand is supporting your head. Bring your right leg slightly forward and bend the knee about 90 degrees. Keeping your shoulders and hips stacked, abs tight, and left leg straight, engage your outer thigh to lift your left leg about 45-degrees off the ground. Pause, then lower with control. That's one rep.
