What is the best way to build your forearms? Wrist curls and extensions? Well, those are certainly the most popular methods but that’s only for a lack of creativity and the sad relegation of forearms to a silent bodypart in the quest for a better physique. It’s time to get your forearms growing. And there are far more ways to do it than you might think.
While hang-holding objects for grip is reliable for building a vise-like grip, for size improvement, you need to follow the same basic rules of development that you use for your other muscles: use heavier weight, perform fewer reps and add lots of volume to your program
Sure you can do the standard wrist curls and extensions with heavy dumbbells or even a few sets of hammer curls. Or, you can do a few extra things and really see your forearms grow. First, check out clubbells. While most gyms do not have them, you can get yourself a couple different sizes and do some hammer extensions and flexions (known as abduction and adduction) as well as pronating and supinating your arm extended out from supports.
If you don’t want to buy clubbells, disassemble one side of your dumbbell or grab a short-bar attachment and you are ready to rock.
Another underused method of building grip and forearm strength is the towel pull-up. Hang a towel over a high bar, grab tight at either end and do your pull-ups.
Another solid forearm incorporator is the fat bar, a standard length barbell that is a little thicker in diameter than the standard 1-inch Olympic barbell. You perform exercises with a fat bar just the same except that the barbell is much harder to hold since your thumb and fingers can’t overlap. This forces the wrist flexors to fire on every rep just to keep your grip.
