How often do you lift? If you lift with the same muscles every day for a while you're muscles will get fatigued at first and eventually you will plateau. The fact that you can't do many push ups is because of fatigue. Take about 2 days off and on the third day lift hard, you will probably notice that you might be able to do another rep on the bench press. However, you will notice a dramatic increase in you're number of push ups because you're muscles will be rested therefore their endurance will be better. This is why many athletes "taper" before a big event. They train hard for months and then the week before the event they take off a week so their muscles repair themselves.
