Dyna Disc Balance Cushion - Royal Blue
The DYNADISCTM balance cushion has become a staple in training & exercise rooms across the country. The DYNA DISCTM works your core muscles more completely than a gymball because it focuses on those muscles no matter what position you are in. Use it at home and then take it with you to the gym. Slip it into your suitcase when you travel so that you can have a core workout in the hotel room.
