Worrying about definition is sad, IMHO. It's nothing but vanity, which nobody except teens care about. If you're fit and healthy, you'll look it, whether or not you have definition.

If you're looking for something more functional, total muscle mass with a little flab is far more useful. God help you if someone like that gets you to the floor.
