Most retards use olympic swimmers to make their case that swimming alone builds muscle and burns fat; it doesn't.
Olympians are considered the best of the best. They workout on top of practicing their sport.
For a better representation look at high school/college level swimmers. They're all slim with little muscle.
Also you'll never have "huge muscle mass" or look like a roid monkey accidentally so don't worry about it you retard.
