Lower-Body Circuit, Exercise 3: Forearm Side Plank With Abduction
Begin by lying on your left side. Bring your left elbow directly under your left shoulder. Engage your core, press your left elbow into the floor, and rise up into side elbow plank. Do not drop your hips.
Place your right hand behind your ear with your elbow out wide or put your right hand on your hip.
Lift the right leg up just higher than your top hip (about two inches) and back down while keeping the hips lifted and your spine long. Do not rotate your body.
