Train The Brachialis For Thicher Arms

If you’re trying to build bigger arm muscles through weight training you obviously need to do tricep and bicep workouts. However, there is a small muscle called the brachialis that lies between the bis and tris on the ousides of the arms that you also need to train for optimal arm muscle size. Targeting the brachialis with a few sets during your biceps training routine will help give your arms a thicker look.
