I understand that you really want to have the knife-like muscles of bodybuilders when they perform on the stage.
But I can tell you that's impossible. Because bodybuilders will go through a hard process of reducing fat before the game, and then show their most beautiful side to the audience.
However, you have to understand that it is impossible for bodybuilders to maintain those muscles when they walk off the stage. Because maintaining that kind of muscle means a completely oil-free diet. It doesn't have much impact on health in the short term, but it is harmful to health in the long run. A person's body must have fat. Without fat, there is no health.
Therefore, once bodybuilders step off the stage, their lines can't be as good as they were on the stage.
So, I think you have gone into a misunderstanding and an extreme.
What do we exercise for?
I think the first thing is to have a healthy body, then cultivate our strong willpower, face life with a positive attitude, and then shape a strong body.
