That's because ordinary people only see swimmers swimming and don't know what training they usually do. Swimming is not only fast, but also the strength seriously affects swimming ability. Therefore, the training of swimmers also includes many training contents to improve the strength level. Besides water training, swimmers also have special land training. Among them, comprehensive strength training will also include bench press, waist and abdomen training, squat, high pull and so on. These strength training movements are the main reasons for the muscular development of swimmers. Think about what ordinary swimmers usually practice. Some people work hard and go to the swimming pool four or five times a week. Doing so can make him slim at best, but it can't make him strong.

Now we can make a summary:

First, ordinary people can't get a better figure by swimming because they are not "training" but "swimming".

Secondly, if you often go swimming, you are still fat, which means that you are not doing well in exercise frequency, exercise duration and exercise intensity.

Third, simple swimming (and other aerobic exercises) can only make people slim. If you want to build strong muscles, you must also carry out necessary strength training at the same time. Finally, it is necessary to remind the friends who love swimming that in addition to exercise, diet must also be controlled, and a two-pronged approach can train an ideal figure!
