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.
Hold for 10 seconds. This completes one rep.
Repeat on the other side to complete a set. Begin with two sets of 10-second holds.
Be sure to focus on your form and abdominal engagement. As you get stronger, increase how long you hold the plank for sets and reps.
If you cannot hold a side plank, start with a side bridge.
