One minute, one powerful hand.

Did you know that you also need to exercise your hands, forearms and wrists? If your job requires you to use your hands all the time, you need something that can work them out. Use the NSD Spinner, a tiny ball of energy that functions as a handheld exercise instructor. It provides the resistance training that your wrists, hands and forearms need. It also improves your grip and relieves pain and injuries including tendonitis, carpel tunnel syndrome and RSI.
