Summary Introduction
Introduction:
Every athlete therefore develops a physique that is typical for that specific sport.long distance runnershave a rather wiry physique yet sprintersare very muscular, even though the movement and thus the muscle groups they train are very similar. The secret therefore lies not in the movement, but in the intensity and duration.
