Start in a full plank position with your arms straight and your wrists directly below your shoulders. Keep your spine long and core muscles engaged.
Bend your elbows to lower into a push-up. Pause, then slowly straighten arms. (Drop to your knees to modify the movement.)
Now, lift your left arm toward the ceiling and rotate your body to the left, shifting your weight onto your right hand, creating a “T” while lifting your hips to the sky. Then, slowly reverse the move. Be sure to alternate sides with each rep. Do 8-12 reps on each side.
