Following the small wrists thread, the situation is like this. My wrists are about 6.75 inches and my fingers and forearms are quite skinny. Most RTW shirts or jackets have too much space between sleeve and hand. I have started lifting weights and was thinking if I needed an isolation exercise for the forearms, fingers, etc. Is thing worth buying? http://www.amazon.co.uk/gp/product/B...pf_rd_i=468294 It's something I can use anytime I feel like but will it help me gain muscle or volume? Or it will just increase my strength? Or it's generally useless?
