How many Push-Ups can you do?

What I used to do for my PT tests....

First the pushups: 40/min, situps: 50/min, and the 1.5 mile run: 14 minutes or less. Nothing really strenuous.

I still do the above (in addition to soccer scrimmage and basketball, plus the cardio machines). I've been subbing the treadmill for the track in the 1.5 mile jog. My knee is starting to give.

if we talking abt doing them push ups correctly with nice form. then probably 30 in 1 sitting. before i can alot more. haven't worked out in over a yr -_-
