Ted-P said:It builds muscular endurance.
I think this is the main point of confussion here...doing the sprints is how to get the benefit for cardio (lungs and heart mainly with some benefit towards the legs) but doing it for press ups or thrusters etc (allthough having some benefit for lungs obviously) is more of a muscular endurance drill and effects the muscles and heart.
