1. Bend 1 knee and straighten the other leg off to the side
2. Make sure the leg is straight and the foot stays flat on the floor throughout the movement - your foot will come off if it's too far away, so you may have to readjust it
3. Make sure your hands are shoulder width apart
4. Rock the body backwards, bringing your butt closer to the floor. Do not rock back towards the foot on the floor! Keep your body position midline.
5. Hold for a few seconds, and repeat on other side.
