Alright so I have a friend that is trying to workout of the arms. I told her to do some light bench presses but then I read somewhere that it effects your boob size if you're a girl. So..basically my question is which excercise routines should she do that will tone the arms but not the chest at the same time. She's not looking at any big muscle building or anything like that. It's basically cutting the fat and defining it more i guess.
Thanks in advance
