I used to have one of those large inflatable balls. I also had a coffee table until it shot out from underneath me and propelled me onto the table! Exercise and me don't really get on!
@johnfalconer The big ball is used for balance and core strengthening. Sit on it and lean back a little like a sit-up. You have to use a lot more muscles in your core to not roll off. Or we lie on the floor and put our feet on it and then bridge up.
👌 I’d probably break my other leg!!!
