Lay on the floor on your side and position your forearm perpendicular to your body with your elbow directly beneath your shoulder.
Place your upper leg directly on top of your lower leg and keep your knees and hips straight.
Raise your body upward by pressing your elbow into the floor until your upper arm is fully straightened and your entire body forms a straight line. Contract your abs hard, keep your entire body tight, and hold this position for the prescribed time frame.
