All participants except the front and back of the group lie down parallel in a row (facing the floor). There is a distance of one to two metres between the participants. The participant at the beginning of the chain has a ball at the start. On his or her command, the lying participants move into the push-up position and form a tunnel. The participant in front rolls the ball through the tunnel and then lies down in the row. On the other side of the tunnel, the ball is caught by the second standing participant (last in the row). The latter then hops over the participants who are lying down again and then rolls the ball through the tunnel. The last participant in the row becomes the new ball catcher. If the thrower does not roll the ball correctly through the tunnel or it does not reach the catcher, the attempt must be repeated (as often as necessary until it works).
Possible competition format: The winner is the group in which all participants have first rolled the ball through the tunnel once (or several times) and the whole group is back in a standing position.
