Reverse Clamshell

Step 1. Lie on your side with your hips and knees bent, keeping your knees stacked on top of each other. Keep your feet together at first, then keep your knees touching while lifting your top foot upward. Slowly lower the foot back down with control.

Step 2. Move only through the hip and avoid rolling your pelvis backward. The movement should be small, controlled, and focused on hip rotation.
