Begin in a plank position and roll to your right side allowing your feet to roll too, so you're balancing on the outside of your right foot and the inside of your left. To advance this move, stack your right foot on top of your left.
Reach your left arm toward the ceiling and lift your waist away from the floor to make your obliques fire away.
To take pressure off of your wrist, press your right fingertips into the floor.
Hold for 30 seconds; work toward holding this position for a full minute. To complete a rep, repeat on the other side.
