Lie on your right side with your feet stacked. Prop up your lower body on your forearm and elbow, pressing your shoulder down and away from your neck. Inhale.
Exhale, lifting your hips up into a side plank so that your body forms a straight line from head to toe with only the right forearm and foot touching the ground. Place your left hand on your hip and keep the line from shoulder to shoulder perpendicular to the ground. Inhale.
Exhale, and raise the left leg up as high as you can, then inhale as you lower it back down to hover over the right foot. When all repetitions are complete, repeat on the opposite side.
