Would you like to run full speed and only exert the amount of energy as it takes you to take one step?

Answer 1

Why?  What advantage would that confer?  What's wrong with running, or walking or anything else that we do?   

Answer 2

No.  I can't run full speed.  I don't run normally and perfectly.

Answer 3

I already do thanks to antigravity tech I brought back with me from the future. It's so much easier on my bad knees.
