3D Nutrition Arm Buster

3D Nutrition Arm Buster is designed to ensure strict form when performing bicep curl movements. By keeping your elbows fixed at your sides, there is no swinging of the arm to take tension off the bicep and assist with curls. This not only prevents you from 'ego' lifting (lifting a weight that is too heavy) but keeps constant tension on the biceps, inducing rapid bicep growth. The Arm Buster also increases muscle pumps during training and provides many of the benefits of a seated preacher curl, but without the hassle. Bust your arms into the next dimension with the 3D Arm Buster!
