At the gym where I train I have seen two lifting bars that I have never seen elsewhere:

1) A standard length EZ curl bar, with a ponounced U shape bend in the middle, and the two curves in the bar on ether side are at a much sharper angle than usual EZ curl bars I am thinking this bar can be used for BB hammer curls and some tricep extensions and pressing exercises??

2) An Olympic length and size EZ curl bar which is obviously used for arm exercises, but I always see it perched on a bench press station,stripped or wiht weights stll on it. Is there any advantage to doing BB benches with this Olympic weight and sized EZ curl bar?

Anyone run into or use these types of bars for lifting?
