endurance athletes are laughing

Athletes are not the same as normal people, who have 1h or so a day to exercise.

You can't outrun a bad diet is a common saying around my parts.

plenty of endurance athletes are pudgy, not lean at all . Usain Bolt is leaner than many endurance athletes. Training for endurance and being lean are different. Some runners get a nice toned body, but this far from the norm.
