Set up two cones about 5 yards away from each other horizontally- as shown below.
Attackers are on one side and defenders are on the other side of the cone.
Both the attacker and defender will be shuffling between their cones (without sticks) with the attacker leading and the defender is mirroring, the attacker periodically throw up their hand right by their head (where they would cradle their stick) and the defender (using the hand their stick would be in) has to reach out and slap their hand.
The attacker shouldn’t keep their hand there for more than 1-2 seconds and the defender should keep her eyes set on her attacker/her hips.
