Lie on your side with your elbow directly under your shoulder and knee closet to ground bent at 90 degrees, with your top leg should be straight. Stack your hips, shoulders, and knees in a straight line. Keep your bent knee foot behind you and your top hand on your hip or in the air. Press through your bottom knee and forearm to lift your hips off the floor. Raise your top leg so your body forms a straight line from head to toe. Engage your core and glutes to stay stable. Keep your hips lifted and avoid letting them sag. Hold for the set time, then lower with control. Repeat on the other side.
