A good way to build forearm strength is to crumple up newspaper. You should lay a piece of newspaper on any flat surface. Using your dominant hand, start with one corner of the newspaper and begin crumpling. You should crumple for about 30 seconds. After you have finished that, switch hands.

In between your workouts, you should try and change the grip on the bar that you use. Some people use a medium grip, while others use a large or wide grip. Changing the grip actually changes the type of muscle that you can work out, and you can get a variety of work outs for a single bar.
