Extend your top arm for an added balance challenge, and remember to do equal reps on both sides.
- Begin in a side elbow plank on your right side with straight legs and your feet stacked.
- Inhale and lower your pelvis to the floor, so your right hip hovers just off the floor. Exhale and press up through your right waist to lift your pelvis and return to side plank. Pull your right shoulder blade down your back to stabilize your shoulder.
