For each pair/trio, set out a 2 meter by 1 meter rectangle with four different colored hats.
1 player stands in the box, the other watches.
Put two lines on each side of the rectangle.
The players in the box have their feet move - dribble - in place.
The players are always given commands to respond to.
Each time you name a color of a hat, they must touch that hat with their hand.
The command line means they must sprint to one of the sidelines. At that point, the other of the pair/triplet enters the box and then does the commands.
Each does this 10 times.
Assignments can include jump, squat, touch heel, touch knee, hop right, hop left, sit, plank, push-up, etc. You alternate these assignments with a color of a hat.
