The unique feature of a lever curl bar is that it modifies the strength curve of a curl so that the top portion of the movement, which would be the easiest part in a traditional set up (e.g. with a barbell), still remains challenging, and hence keeps your biceps engaged. As a result of this, you can get a crazy pump using the lever curl bar. Also, because the strength curve created by this bar is more challenging, you'll be able to use about 1/2 of your normal curling weight. The build quality of the bar is what you'd come to expect from Gorilla Strength Equipment. David and his family do a fantastic job in creating gym equipment that are robust and can take a beating. Despite this, I'm docking couple of stars from "Value" because biceps training isn't a priority for me. I like to rotate this into my arm training when curls with a normal ez bar becomes stale. It helps to add a new stimulus to keep training fresh and fun. Also, if you already have access to a preacher curl bench, or a preacher pad (e.g. AbMat's), you're going to get nearly all the biceps gains that you can hope to get from using this bar.
