The original exercise balance device, DynaDisc is an inflatable balance cushion (supports up to 2000lbs/sq. inch). It's smooth on one side and textured with pegs on the other. Use DynaDisc seated to provide benefits similar to a gymball, standing to increase balance and muscular resistance while doing exercises, or lying to improve core strength & stabilization during floor exercises. Vary inflation to change the degree of difficulty. Dynadiscs improves posture, alignment and create a more challenging workout in less time. Two-year guarantee.
Please Note: Dynadiscs require a standard ball needle and pump to inflate. If you don't already have one, please purchase separately.
