Customer questions & answers
1.What is the material inside the wrist ball? Will it rust?
Mostly plastic with a little metal, it's pretty well enclosed you would have to intentionally try to sweat inside of it to make it rust
2.People don’t seem to understand my concern? The last image shows the tricep as being the muscle in the front. This is incorrect
It’s a potential side effect of the powerful gyroscopic force. At high RPMs the torsion has literally caused some users’ upper arm muscles to swap positions.
3.How much force is produced while using
As you gradually increase your core speed, you will feel the same synchronously increasing reaction force rotating gyroscope on your wrist and arm.
