Neodymium Immortality Rings, Vibrations, Centrifugal Forces!Guys I am thinking of buying one of these and exercising using this tool while I wear my immortality rings

I heard that it is good for building active stability and rehab.
I get very sore wrists and DOMS from hanging onto my chin bar as long as possible because I am trying to stretch my back very long so that my intervertebral discs become plump with fluid and the ligaments stretch so that I can bend further forward and backwards.
It would also stretch core muscles like abs obliques and lower back.
But the hands get so cramped so I wonder if the immortality rings would enhance working out with a gyroball.
