Male model fitness generally needs to focus on modifying the size and lines of chest, abdomen, back and shoulders, but the bigger the better, which is different from previous bodybuilding. For male models, muscle lines are far more important than muscle size. The back should not be too thick, the hypotenuse should not be too big, and the thigh muscles should not be too thick. When you have time, you can find some well-known domestic model websites, such as China Model Online, which should have knowledge about male model fitness.
