Tescos £5 for a workout ball. You just sit and bounce if you like.
Here's a few exercises you can do:
bounce and control yourself to stop dead whilst bouncing, so 5 bounced then stop dead. This helps your core muscles contract and strengthen.
Sitting on the ball, walk down so the ball is on your back and your legs are bent. Rock in as out bending and staightening your legs, this is a leg exercise. When youfeel comfy with that, take one leg away and do it 1 legged. Very good for balance and core, only do it if you feel you can.
Sitting on the ball, hold a can of baked beans in each hand, keep arms straight down beside you,then lift both arms up to shoulder level, then back down. Repeat 15-20 times. This strengthens shoulders.
I've got hundreds more, so pm me If any of you want more. Sorry that they may not make sense as it's hard to describe with out demonstrating. I teach a class on the fit balls 2x a week. Feel free to ask! Xx
