Like ordinary people's amateur fitness, the body fat rate should be controlled, but not too low. Adult males range from 10 to 18, and adult females range from 16-22. The "training trace" is also obvious.
If classical bodybuilding is the goal, training will be divided into rest period (muscle gain period) and seasonal period (fat loss period). Male professional players' body fat will be below 8, and some can reach 3, but most people can't.
Fitness can also include "strong men", only absolute strength, not weight. As you can imagine, this body fat rate does not need to be controlled. As long as you have the strength, you can be fat.
