Why Use Two Legs?

I've searched so many lists online for push-ups variations, so I don't know why it took me so long to think of using one leg. I've revamped my push-up routine for next week. I'm on Week 22. I've dropped the rotational ones and added 5 one-leg variations. I would say, "Hopefully this doesn't jack-up my legs," but I want it to.
