Its not something I commonly due. Especially because I dont want to look like an ego maniac and a goof flexing in front of the mirror near everyone in the gym. But, does it really have any physiological effect on the muscle, as far as filling it out and making it more defined? I have heard some people say that it can do things like create a higher bicep peak, and so on and so on. But can anyone attest to this?
