Infinity Arm Blaster

BUILT FOR SERIOUS CURLS Crafted from 0.25" thick laser-cut aluminum with your choice of leather or nylon strap, this essential training tool keeps your elbows locked in and your form strict during curls and triceps work. By preventing arm flare and eliminating momentum, it forces maximum bicep isolation, so every rep hits harder and builds stronger.
