One should consider fitness for sport.
A marathon runner will not be able to lift heavy weights. Indeed, running extreme distances can denude muscle. The marathon runner can go the distance but its important to understand that this can come at a cost. Lets take a body builder. The large muscle mass requires a large calorie input. Muscles need food. So a body builder is burning lost of calories, even while sleeping. A marathon runner is lean with little mass. It does not aid winning a marathon to be carrying extra muscle. So the physique of the runner with be lithe. The marathon runner in the latter stages of the race is switching from burning fat resources the glycogen stored in the muscle. The other issue is a runner is not going to train muscles they are not using. So a bench press is rarely in a marathon training plan. The importance of the core cannot be over emphasised. Strong core; strong finish
