Found out about airex balance pads via my gym. this is a pricey item, but something so simple and effective.  Couch potatoes can purchase and when you are watching TV just practice standing on it for balance. Then stand on one foot for balance. lift weights while standing on the pad. Use it to do lunges.  I gave one to my exercise buddy and she and her husband fight over sitting on it while watching TV. lol  they also use to kneel on when giving their grand daughter a bath.  I like it!
