As with any exercise you do gain muscle mass. but your forearms,calfs, and abs are stubborn muscles that are made to take a daily beating. After using the power ball for a week or two you should notice a lot more refinment in your forearms but it will take time and a lot of work to add mass to them. keep using the powerball
