- Lay with the small of your back against the round side of a Bosu ball. Your knees should be bent with your feet flat on the ground. Fold your arms across your chest. This will be your starting position.
- Perform the movement by flexing the lumbar spine raising your torso. Do not flex the hips.
- At the top of the motion pause, and then return to the starting position.
