From the elbow plank, place both hands on the ground, one after the other, to come into a high plank. Ensure that your shoulders are directly over your wrists and your core is braced.
Shift your weight to the right as you lift your left hand off the ground and turn onto the outside edge of your right foot. Place your left foot on top of your right foot, ensuring that your body is in one straight line. (To modify, place your left your leg on the ground in front of your right foot.)
Pull your core in toward your spine and use your obliques to lift up from your right waist. Keep your body in a straight line and avoid dipping your waist down.
