Q. Do those things you grip and squeeze really do anything for your hands or wrist? What about those stress balls or squeezing a tennis ball - or is that all hype?
I broke my wrist when i was much younger and I still don't have the same strength in that hand as in my other. Would these things help?
Grippers, stress balls, tennis balls, etc. are all tools that one can use as resistance to strengthen the muscles of the wrist and hand.
One set of as many grips as you can do (until you're tired), every other day should do the trick.
It's a good idea to still work the other (stronger) hand.
