After buying this I now realize there's not much more benefit than say an ez curl bar or dumbells as far as triceps are concerned. You can easily use an ez bar or dumbells to get the same exercise. Also when you rotate the handles doing triceps it's dangerous because the bar is no longer supported. I suppose they did that function for curls. The bar itself is kind of awkward in general to hold because it's not really supported from every angle. You always have to be mindful to hold it a certain way to avoid it slipping and potentially banging you in the head. I think I was attracted to how cool it looked in the beginning and didn't think it through overall Anyway the best thing about it is it's actually pretty versatile in that you can use it for tricep extensions, curls, chest press, and upright rows. But ultimately you don't NEED this bar. These exercises can be done with other bars or dumbells just as good or better
