In my other sport, well, it's not a sport but anyway in Aikido push ups are often a part of warm ups. I used to rip off 20 and even the "fancy" ones, finger tip, on the fists, backwards, back of the wrist..

I still like putting one foot behind the other so more weight's on my arms. I can manage 10 now. Used to think that was just 'cause there's more of me to lift but, yeah, I'm out of shape.
