With your feet facing the left side of the room, place your hands on the floor shoulder width apart and your right foot in front of the left foot (heel to toe) with a towel under your feet.
Using your side waist (oblique) to pull, slide your feet/legs a few inches closer to your hands.
Next slide your feet/legs away from your hands. This completes one rep.
Focus on using your side waist (aka oblique) to do the work. Avoid bending your knees.
