These high-tech, light "gyrohandles" would be unencumbered by wires, ropes or elastic cords but would resist movement in all directions. Using technology similar to anti-shake film cameras, each dumbbell would enclose gyroscopes. The dumbbell rack would power up the gyros and/or recharge possible batteries
in the dumbells. The user could choose the rpm to provide a suitable resistance level and use them on the hands or feet for overall training.

Kind of baked here [faffer]
As an aside, a good visual explanation of how gyros work.

"recharge possible batteries"
Aha! - now there's the REAL innovation - schodinger batteries. Methinks its that quantum again. |

Gyroscopes are good for converting attempted rotation away from its axis into procession about its axis, but don't do squat to resist linear translation. |
|
| |
Dumbells might not be the best choice for gyroscopic reactions. That wrist exerciser link appears to have the idea though. |

I have one of those Powerball things, and it really does work. Loud, though. They're wrong about the maximum speed, though; the site I bought mine from Long Ago had one with a speedo on it, showing more than 13k RPM. |

| |
It is greatly amusing to get it going really well then hand it to someone... |
|
| |
Mine got dropped and broken, glued back together, dropped again and reglued, which makes it even louder than it was to begin with. I want one of the metal ones... |
|

just looked at this powerball thing, boys. genuine girly question coming up - do you alternate hands ? |
|
| |
Eventually. I usually do it till one arm gets tired, then switch. <grin. Yes, I know what that sounds like.> |
|
| |
<grins back> Would it help my RSI? |
|
| |
The site claims it will help. I only ever get it in one finger, so I can't really say. |
