Gyroscope powerballs

[Sascha6990]

It's the second time I own a powerball, I think they are awesome for training your wrist, fingers and forearm strength, of course depending on how fast you're spinning it. I also noticed they effectively lower stress, kind of like a squishy ball on steroids

Is anybody else using one? I was thinking about whether the vibrations it is causing in the arm could be in any way damaging. At high speeds I can even feel my shoulder vibrating.

Here is a video demonstrating how it works

And a guy hitting 22000 rpms which is insane

I bought one of these about 25 years ago, I have it somewhere?? Need to find it, would be good to use now that I'm older and lazier haha. it takes some practice to get the inertia going properly and I assume some can't do it.

I had one of these when I was a teenager. Unfortunately, at that time I decided to "train" my forearm strength by other means.

I'll have to check if that thing is still lying around somewhere in my parents' house. It was fun. Never thought about it as a means to lower stress.

lol. The technique of the guy who got it up to 22,011 rpm in that 2nd video looks he had lots of practice
