What is this exercise called?

A gymnastics coach taught it to me; it looks like an inch-worm and I think it may help develop wheels.

After I did it the first time in the gym, I noticed someone else trying it out.

I call them hands feet, hands feet as a type of animal walk/run. Typically we race across the gym floor and it looks like some sort of 4 legged animal running around. Rather, they usually go at that pace but I demonstrate it as a run, except there is a danger of face planting.

I should probably call it manimal bounding or manimals.
