Coach Burgener shared partner jumping with us as a tool he uses with some of his physical education classes. No-equipment-needed, anytime-anywhere plyometric training.
The static partner (the one sitting) sets up with legs together, straight out in front, and arms straight out to the sides, at shoulder height. The jumping partner starts with feet together, facing the same direction as the static partner (position 1). Jumping forward over the raised arm to position 2, the jumper turns his toes toward the sitter's legs, jumps over them to position 3, and then turns his toes toward the raised arm and finishes one round by jumping the arm and landing in position 4. For the second round, the jumper turns to face the same direction as the static partner and repeats the sequence in the opposite direction.
Take big jumps, pull the knees up--get tall!--and then land and rebound into the next jump.
