 Build an incredible chest and an incredible back with this one tip. 20 push-ups five times during the day. This is called greasing the groove or practicing the movement. Let's say you could do 10 pull-ups all at once. Well then why don't you try doing three pull-ups five times a day. Just walk by a pull-up bar, do three pull-ups, and then maybe an hour or two later do it again. Practice all day long. Watch what happens to your strength.
