Pros: very nice gains
Cons: made me itchy
Before using this my biceps were stuck at 20 inches for 3 years. I didn't think they would ever grow anymore. But after using the arm blaster for 7 weeks my biceps grew to 21 inches! I am so happy. Currently my biceps are 21 1\2 inches and I think the super arm blaster will help them to continue to grow. Before using the Super Arm Blaster I was cheating to do curls. But now I simply hang the Super Arm Blaster over my neck and put my elbows against the pad. Doing this isolates my biceps for maximum growth. I have had the Super Arm Blaster for 10 months and it looks just like it did when I bought it. I hope this review is helpful.
