Is the cable cross-over a useless excerise to do when your not cut/all that defined?......personally, I am not cut or the most defined individual, however, I do this excercise sometimes as the last 1 when training chest.......I've read and have heard both sides of this argument......BUT, I like doing this excercise simply b/c it feels really good and can really feel the pecs working, that's why I do them.........even though, there is ALWAYS gonna be some shithead (who thinks they know everything there is to know abt "excercise science") that's gonna say" why you doing those b/c you don't have the definition to bring out what that exercise if for".....
