1 - Stand tall with your feet about hip-width apart, arms relaxed at your sides, and your body facing the sprint direction.
2 - Shift your weight onto the balls of your feet and slowly lean your whole body forward from the ankles while keeping a straight line from head to heels.
3 - Continue leaning until you feel you must step forward to prevent falling; do not bend at the waist or look down excessively.
4 - As you begin to fall, drive one knee forward and opposite arm back aggressively to initiate the sprint.
5 - Accelerate powerfully for the prescribed distance, staying low through the first few steps with strong arm action and quick ground contacts.
6 - Gradually decelerate after the sprint zone, walk back to recover, and repeat for the desired number of repetitions.
