Muscle Group: Biceps
Equipment needed: Arm Blaster
Curls with an Arm Blaster are a very strict way of working the biceps. If you are serious about your bodybuilding training you may want to look into getting one of these. An Arm Blaster cuts down cheating big time and they run for about $30 bucks on Amazon.
By using the Arm Blaster, you get the same kind of effect as with a preacher bench – no elbow movement at all and a hardcore isolation for your guns.
