Step by step instructions
Kneel on all fours with your wrists aligned under your shoulders and your knees under your hips, and place a light dumbbell behind your right knee. Raise your left arm to shoulder height in front of you, palm facing the ground. (Beginners, keep both hands on the ground.) Lift your right thigh to hip height behind you, foot flexed. Return to starting position and repeat. Switch sides to complete set. Pull your abs in tight to help activate your core and stabilize your body.
