Saludos, I am planning to build a rocker plate and wondering if those of you that have built one can share your experience on the pros and cons of using tennis balls vs air tubes or air balls. I think that air tubes should provide a less bouncy surface, however, a lot of DIY plans recommend tennis balls.
Gracias, Manuel
I got cheap extra thick (25mm) yoga mat from Amazon and put my trainer on that. The mat still took up a lot of space when rolled up, so eventually I just cut two strips off it, and zip tied them to the bottom of my trainer. Cheap, easy, takes up no space, and gives just enough lateral movement to prevent discomfort without being too wobbly.
