Besides, who said swimming can keep fit? Unrealistic. It seems that without actual combat, it can hardly shape anything. It is ok to play in the water.
The figure and appearance are the same. It's all from my parents. Let's admit it.
Some people will say, what will happen to some people after fitness? Excuse me, will the body occupied by improper means be maintained? In the audience, even if it becomes your dream posture, how many days and nights do you have to endure (eat less, dare not eat, be tired to death and exercise).
So I think we should let nature take its course.
