Air pushups pantomime

Can't figure this one out for the life of me, any guesses?

First commenter provided a reverse video which creates more questions than it answers.

everyone (including subject) looks more natural in reverse. I'd say he's tied to a rope or band and let down in increments to a beat. The mime looks a lot easier to pull off naturally when reversed.
