The best bicep machine ever made. I have another in my own gym. Hit your biceps in three unique ways to triple the results in both strength and size by changing where in the movement is hardest (start, middle, end). Exhaust the beginning like your average bicep machine then do the same for the other two positions and you just got 3x the work in without lowering the weight to completely exhaust the muscle. Featured all over the internet you can see for yourself why people love this machine so much.
