I've seen video of min yung kim doing one-handed pushups at a show; I can't do those, but I usually do 20-30 pushups every morning along with various other exercises (pullups, crunches, etc.) before going to work. I don't know how many I can do at max, though. That's just to get the blood flowing and the metabolism going, since I tend to get my real workouts in the evening. These are military style pushups, slow and steady, not girly ones.
