- Try to lift your bum up off the floor and get yourself into a nice, tight, cannonball.
- Return your feet to the floor under control.
- Make sure your lower back is flat on the floor before your feet touch the floor.
- Arching your lower back off the floor at the start/end of the move.

Comments: Many people find this move difficult at the start, but it is a very good "core" exercise. I use this to help people who are having trouble with their Planks, Wheelbarrows, Pressups and people with poor posture. This can help towards correcting an over arched lower back, or anterior pelvic tilt.
