My chest sucks. I train it once a week with typical dumbbells and barbells and machines.
But, every day, I do 4 sets of pushups or 4 sets of resistant bands presses before bed.
Do low incline flyes ( 30 degrees good stretch) immediately followed by Smith Inclines to the throat........no rest..............rest a minute ......repeat and do nothing else except to finish off with a max rep set of parallel bar dips.
15 reps,12 reps,10 reps,8 reps adding weight each set brief rest periods leave your ego at the door.
Those pushups are bb.com shit and wont do a helluva lot for you my brother.
