Bosu

A workout that is great for muscle conditioning, body awareness, alignment and co-ordination uses a Bosu (“both sides up”). It’s a dome-shaped rubbery surface (fab for toning abs), turn it over and it’s an unstable disc (perfect for honing balance and co-ordination). It’s used by personal trainers, or buy a Bosu and workout video from Physical Company ( £149.50, 01494 769222).
