The Vew-Do Rocks are available in a variety of progressions, perfect for pushing your skills or rehab. Maybe you purchased a Zippy and now are ready for more advanced training, or you might have a Zone and need to add another element to your strength development.
Spare rocks are excellent ways to make the most of your Vew-Do training.
The urethane Wobble Rock from the Zone package is also available seperately for those who want to use it with their regular Vew-Do balance board and add a little more entry level training option.
