Coach John Walker puts his athletes through and insane footwork and conditioning workout to help them develop better overall foot speed, and the ability to keep pushing at a high level without getting tired. 

The purpose of these workouts is to keep high energy output so that you can push much longer than your opponent during competition.  Do not be discouraged if you cannot finish these sequence of drills all together as the athletes depicted in the video have been training for months prior to this workout.
