Yoga ball cut in half on black flat platform, what is that piece of equipment called?
Bally's and 24 hour fitness who sponsor the biggest loser have a piece of equipment that looks like a yoga or balance ball that has been cut in half and put on a round black disk style platform that people can either stand on the ball side or flip it over to use it for balancing when doing upper body exercises. I can't figure out what this piece of equipment is called so that I can buy one. Does anyone know what it is called or where I can find one? Thanks!
You can purchase one at..
-Linens 'n Things
-Dicks Sporting Goods
-Mostly any store that would carry a normal yoga/balance ball.
They usually run about $100.
