For an intense field (or parking lot) exercise that really gets the blood pumping and the legs churning, trainers turn to weighted sleds. While the original intent for sleds of this type was to train football linemen, several fantastic sled techniques have been developed to build leg strength, speed, explosiveness, acceleration and overall athletic conditioning. Resistance Sleds help to improve acceleration with weight resisted sprints. Heavy-duty sled designs allows for great short burst training, use while running hills to intensify an endurance workout, or use handles for push training.
