Kneading 'fit you ...

I find the green ball is a perfect training tool for passing.
First, I had a feeling he might be a little too small and too soft, but the size is ideal, since one hand then press very far along / needs and the strength of a people with "normal" force also good. That will be do with the money that you can rumkneten it over a long period.
A real muscle building so far I could not identify, but my kneading falls definitely in time a little easier.

It is not entirely so hot that the green ball glued animal. After calming time he is full of lint, hair and all the other little things. He does not stick, but is also accordingly disgusting.
Hab washed him again, after that he was still sticky! I do not know how to deal it. But there's one point less.

Otherwise, highly recommended!

Have gained me the red ball, after I had drawn me a metacarpal fracture. After 4 weeks, gypsum I could hardly or not move my hand or my fingers and had absolutely no muscles or no strength.
The physiotherapy has recovered the movement and the red ball to the force!

Several doctors and physical therapists have recommended to me anything like that to use to build muscle.
There has been no miracle, but it works very well! Hab again regained some strength within a few weeks and knead further to myself ...

The red ball is not nearly as tacky as the green counterpart. From the strength I find him right for postgraduate training. (For the other hand it is too soft.)

Highly recommended after fractures, surgeries, etc!
