I tried that, even started doing heels raised on 10 pound plates with a close stance staying strictly up right. Definitely helped my quads, but the glutes remain.
To the OP: Unless you have a chics ass, looking like Alexis Texas or something, I wouldn't worry about it man. There is quite a difference in a muscular man butt, and a female one-- if that is what you're worried about. My girlfriend loves mine, and her among other women I know do not find assless men attractive.
