I do flat bench press in my 3 day workout for my chest and i often do some fles aswell.My lower and side of my chest has come on better than i could of imagined, but my pecs look to seperate if you know what i mean, i want to find an exercisse to work my inner chest or all of my chest as upper chest and inner chest dont get worked on flat bench or flies.For my inner chest im thinking of doing press ups (inward facing hands).Im doing garys all body workout 3 days a week which shoud only involve 1 or 2 exerssise per muscle group per session so doing incline, decline, flies and press ups isnt possible with my routine but i could do 2 exercisses per session without causing overtraining i would of thought but what 2 exercisses would be best for training all of the pec especially inner?.
