I'm not trying to be one of those "dude your form isn't proper" dicks who obviously can't touch the guy's numbers... I'm genuinely curious. I just notice that I can get many more reps when I stop myself from going completely extended at the top, and not "all" the way down at the bottom, and go super fast.
Just wondering what your range of motion and speed are like when you do a set of 125 pushups. That's friggin' insane man, I hope to be at that level some day.
I've been doing them basically extended at the top because I've read it's better for your shoulders, and pretty low, sometimes skimming my nose on the carpet.
