The players are placed in pairs in a great circle.
A number of balls corresponding to 1 or 2 fewer than pairs are placed in the center of the circle.
On signal all the players on the outside of the circle start running (remember to tell the direction).
When the runners returns to their teammate they must slide between the teammates legs or play leapfrog and get to the circle and take a ball.
The team(s) who do not get a ball are "rewarded" with push-ups or something else.

The run can be varied:
The runners must run sideways or backwards and even make them run in different direction around the circle (however not backwards)
