Pushup square

The pushup square is a coordination game for four participants (you can try it few fewer of more players as well).

Equipment
You don't need any equipment.

Procedure
The task is quite simple to explain: the four players should move to a push up position and then put their feet on the neighbors body, so that in the end only their hands touch the floor. Are they strong and agile enough to do that?
