As a small group, you move freely in the hall/area. The sports leader can specify various forms of movement (crossing legs, circling arms, crouching, touching the floor, hopping, one-legged hopping, etc.).

As soon as the sports leader calls out a number, the group stops and forms up so that as many limbs (legs, arms, head or buttocks) touch the floor as specified by the sports leader (e.g. number 5 = 3 legs and 2 arms). Number 5 = 3 legs and 2 arms).
Variant:
The sports leader can request "mandatory limbs" (e.g. 1 head or max. 1 leg).
As soon as the sports leader calls out a number, corresponding groups must be formed (e.g. number 7 = groups of 7). Each participant only looks after themselves. Whoever remains performs an additional exercise defined by the sports leader (e.g. 3 stretch jumps, 5 jumping jacks, 4 push-ups, etc.). If the group size is not correct, all participants in the group must perform the additional exercise; if the group is complete, it is advisable to send newcomers away. After a check of the group formation and execution of the additional exercises, new small groups are formed, which move freely again.
Variant:
The sports leader can define how the group joins together (back to back, prone position and outstretched arms meet at a centre point, one-legged stand and the hands are placed on the shoulders of a group member).
It is also possible to combine both forms of exercise by having the sports leader define the group size and the number of limbs that are allowed to touch the floor (e.g. group of 6 - 5 limbs).
