Answer
Hello,

 You can invest in a training parachute, for running sprints. You can also find a hill in your area, and run sprints up the hill. Stop every 5 to ten yards get in your stance and restart the sprint, until you reach the top of the hill. The training ladder, will help with quickness and footwork.
