SETUP: Set your marker for the designated distance. Start down low, one hand and one knee on the ground.
REP: Explode out of the start position, staying low for the first 10-15 meters and driving yourself forward through your quads. When you reach the finish line, be sure to slow down gradually rather than suddenly stopping.
TIP: Either rest at the finish line and sprint from there or walk back to the start line as you recover.
