Circuit 1, Exercise 4: Side Elbow Plank
- Begin by lying on your side. Bring your right elbow directly under your right shoulder. Engage your core, press your right elbow into the floor, and rise into side elbow plank.
- Stagger your feet so your left foot is just in front of your right, or stack the heels.
- Reach your left arm up toward the ceiling, which will help you lift your waist.
- Hold for 30 seconds, and then repeat on the other side.
