Okolo has decided to have his own set of animated exercises on his website (much like I have done), and he has begun with how to do pushups.

He has an animation of himself doing a pushup, along with instructions of how to do them. He also explains how to do handstand pushups.

Along with my own animated version of how to do pushups, you can also see how to do assisted pushups for those that are not yet comfortable doing regular pushups.
