really fast muscle building

[user]

hi im a guy from Denmark who just bought one of your powerballs, and I am really happy about that investment

When I started my Max rpm was 10.000, but now, only after 9 dayes it has raised to 11.900 , I can really feel how my muscles are working, and already now I can use it for longer times without my arm-muscles hurting.

again, I am really happy with this product!

I don't think a Powerball could build huge muscles, but my arms have certainly never been in such good shape, from my fingers to my shoulders...I've even noticed my lats and pecs are in better shape than ever.

Truly an awesome product.

You just want a Metal now...they produce much more torque!
