A focused arm curl variation where you use an arm blaster to keep your elbows fixed at your sides while lifting a barbell. Stand upright with the arm blaster supporting your upper arms, then curl the barbell upward by bending at the elbows, squeezing the biceps at the top. Lower with control, maintaining tension throughout. This setup isolates the biceps, reduces cheating momentum, and improves peak contraction and muscle definition.
