Do men have a fit athletic body because of muscles?

Having a fit and athletic body is not solely dependent on having muscles. While having well-developed muscles can contribute to a fit appearance, overall fitness and athleticism also involve factors such as cardiovascular endurance, flexibility, and body composition. Men with fit and athletic bodies typically have a combination of muscle strength, cardiovascular fitness, and a healthy body composition. Additionally, factors such as diet, exercise routine, genetics, and lifestyle choices all play a role in achieving and maintaining a fit and athletic physique.

Yes, men who have a fit athletic body typically have more muscle mass than men who do not. Muscles are made up of protein, and protein is essential for building and repairing tissue. When men engage in regular exercise, they stimulate the growth of new muscle tissue. This new muscle tissue helps to give men a more defined and athletic appearance.
