Bow your body like a crescent moon to stretch the muscles in your abdominals.
How to do this pose:
Stand up in the footwell of your Beachcomber. Start with your hands on either side of you body, slow reach up and place your hands together above your head. Slowly arch your back imagining there is a string pulling your chest towards the sky. Be very careful not to over-exert your back. Not recommended for those with lower back problems.
