If you want big forearms, then this might be the best exercise that you've never done.

Most people will train their forearms with simple wrist curls and wrist extensions with either a dumbbell or a barbell. While these are certainly viable exercises to get big forearms, if you've been doing them for a while and you're not getting the results you are looking for, then look no further than this forearm exercise.

The setup is simple; all you need is a band, a barbell in a rack, and either a dumbbell or kettlebell. Simply wrap the band around the handle of the dumbbell or through the handle of the kettlebell while it is resting on the floor. Then, wrap the other end of the band twice around the end of the barbell while it is resting in the rack to make sure it is secure.

Once you have the band setup around both the weight and the barbell, grab the end of the barbell and start rolling it forward with your palms facing down. As you continue to roll the end of the bar, the weight that is attached to the bed will start to ascend upwards towards the bar. You can either roll the bar until the weight reaches the top or your forearms start burning too much that you can't continue rolling the bar, whichever comes first.

This will will engage the forearm flexors and work on the meaty underside of your forearms.

If you want to build the top of the forearms and work your forearm extensors then simply do the same thing but roll the bar towards yourself instead of away from you.

Whichever part of your forearms you are looking to build, you have an option while using the same setup. Perform 2-3 sets in either direction, or both, if you are looking to get big forearms.

If you haven't tried this exercise before, you are going to want to add it to your routine to build bigger forearms. Now, you'll have more options outside of the wrist curls and extensions you have likely been doing before this.
