Lie down and raise the body so that only one part of the body (usually the buttocks are easiest to begin with) remains in contact with the ground and the rest of the body is raised at least a little bit. Slowly move so that a different part of the body makes contact with the ground and the original part is raised instead. A simple way to begin exploring this idea is to make a circle all the way around the body in one direction and then the other.  Cheat as much as is necessary - assist yourself to do the job, but do it honestly. Try to challenge yourself to practise the work cleanly and recognise when you're cheating because you are being lazy rather than cheating to be capable of doing the work.

Remember to breathe - remember to smile and as always- don't hurt yourself.
