Reminds me a shooting drill I did at shoot n move to get your heart rate up and faigue you. You start out with both of your your hands on the target, pistol holstered. At the buzzer you move to the 3 yard line, 3 push ups, and 3 shots. 5 yard line, 5 push ups, 5 shots......all the way out to the 15 yard line....It was fun to run this drill and also to spectate.
