DFX Powerball: IRON Forearm muscle builder

Iron is on a level all its own!!!

I am a long time user of the power ball sport, Iron is on a whole other level. I use the sport to warm up my session with the iron. You can feel the difference in resistance causing your muscles to work in a way you would never have thought before using the iron. I've noticed a change in grip strength from simple tasks of plucking weeds and opening jars.The best overall feeling is the strengthening of the wrist. The dull ache I get from being on a keyboard all day or lifting a heavy grocery bag the wrong way for to long; Iron helps work out the cramp and fatigue.
