Have players line up along the baseline. When whistle goes, the players run the length of the gym, and do 10 wall taps (with both hands) against the wall, and then sprint to the other end and do 9 wall taps. Then sprint to opposite end and do 8 wall taps... Until the players get down to 1 wall tap. After one tap, they do one last sprint.
Jumping and conditioning.
