For the next exercise, you'll move into a side plank. Follow the instructions below, holding the plank for 30 seconds before switching sides.
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 your right or stack the heels.
Reach your left arm up toward the ceiling, which will help you lift your waist.
