Your arms and forearms are greatly engaged when bodybuilding. If you want to focus your efforts on building muscular biceps, triceps and forearms, you need the right tools. A more oversized grip or alternative grip will make it harder on your forearm muscles, leading to better results and muscle growth. Fractional plates can help you perform drop sets to really push your muscle fibers to their limit. Blood flow restriction can lead to better results for the same workout.
