How about an exercise that can make your upper arms and forearms bigger? The reverse barbell curl deceptively looks like a regular barbell curl, but has an important twist!
Reverse Barbell Curls
The big difference to the regular barbell curl is that you do the reverse barbell curl with your hands facing away from you. What that does is move work to your brachioradialis muscle, with a side order of biceps and brachialis involvement. This can make quite a difference for your arms:
Slight Movement Is Ok
As I said in the video, moving the upper arms forward a bit is ok, as it allows for a full range of motion. Some people say that this takes tension out of the muscles for a moment, but to me that doesn’t seem to make any great difference to the effectiveness of the exercise.
