AKA "the Bicep Bomber" this bicep arm curl blaster is great for stabilizing the upper arms and preventing cheating during the arm curl exercise motion. The arm blaster first appeared in fitness clubs in the early 1980's and was made famous by Arnold Schwarzenegger while he was at the peak of his bodybuilding career. Secured by a comfortable neoprene-padded nylon neck harness, the aluminum-backed arm blaster employs dense foam to support the elbows during exercise. A PROVEN way to train the biceps for decades!
