Fab little item and once you get the hang of it its a good workout!, 29 Mar. 2011
Fab item, arrived very quickly for sure. Haven't had any trouble with it slipping on carpet but have a chair at the side of me just in case. The trick is, after reading my physio notes not the instruction ones, is to clench your bum and hold you tummy in as this really helps your core to counteract the wobble. Here's hoping it helps to strengthen my knee after a recent op!!!
