- The arm blaster is a contraption that keeps your elbows in a fixed position. It allows for better engagement and potentially more effective time under tension on the bicep. Go slowly when you can, squeezing each contraction. When you start to fatigue pick up the intensity and rep it out. Leave nothing to fate, numbers win games.Arm blaster bicep curls | |
