Bodybuilding - Building Forearms Muscles
Upper Forearms
Hammer curls, reverse wrist curls, one-arm cable reverse curls (Ex - Shown with two arms), and every other kind of reverse curls really hit this area of the forearms not to mention the biceps.
Inner Forearms
One-arm wrist curls, barbell wrist curls, and behind-the-back curls are excellent inner forearm builders.

"Many bodybuilders end up with a weakness in forearm development simply because they don't train forearms right from the beginning. Another reason for forearms lagging behind, aside from the obvious one of bone structure, is failing to execute the exercises correctly and in a strict enough manner. The more you isolate the forearms and force them to do the movements without any help from the upper arms, the more they will respond. This means being very, very strict in your execution.
"It is important to work the forearms through a long range of motion. You need to lower the weight as far as possible, getting the maximum stretch, then come all the way back up to get a total contraction of the muscles. Working through only three-quarters of the range of motion is not that beneficial because you already use this part of the muscle in a variety of other exercises.
"If you want to drastically increase your forearm development, you can use the Priority Principle in a special way: train forearms by themselves when you are rested and strong, or train your forearms on leg days when your arms are rested. You can also keep a barbell or dumbbells at home and do a couple of sets of Wrist Curls and Reverse Wrist Curls as often as you like, even once an hour every hour." by Arnold Schwarzenegger
