Jog into the start of the drill to increase forward momentum. As you jog, start the drill with the right foot forward and the left foot back.
This drill is simply an exaggerated running action. Push off with the left foot and bring the leg forward, with the knee ben and the thigh parallel to the ground. At the same time reach forward with the right arm. As the left leg comes through, the right leg extends back ad remains extended for the duration of the push-off Hold this extended stride for a brief time, then land on the left foot. The right leg then drives through to the front bent position, the left arm reaches forward, and the left leg extends back. Make each stride long, and try to cover as much distance as possible.
