Just to fill out the other tail of the bell curve...
Name: I-K
Age: 31
Height: 194cm (6'4")
Weight: 105kg (230lb)
Pushups: Palms flat on carpet, feet together on the floor, using strict form; controlling descent all the way down (I have a formerly-smashed elbow which complains otherwise)...
...28 in 60 seconds... oh, the shame.
I had a few more (like, another four, maybe ) in me, but ran out of time... how people manage to cycle through a full pushup in less than a second is beyond me.
