Begin in a side plank on your right elbow with your heels stacked. (If this is too hard, place your top foot on the floor in front of your other foot.)
Inhale and lower your right hip a few inches toward the floor, then exhale to raise your hips back to neutral. Think about pulling your right shoulder blade down your back to stabilize your shoulder.
Continue for 15 seconds, then repeat on the opposite side. Rest for 10 seconds.
