"The response to ZeroWheel from both trainers and members has been incredibly positive. I have had half a dozen of our high usage members (workout more than 5 times per week) say they have not been this sore or fatigued from a core workout in a long time.
Trainers have been using it both with their clients and in small group fitness classes. They trainers report that they are very easy to use, adjust and the clients have caught on quickly."
