There are only two possibilities for shoulder widening. One is that the deltoid muscle becomes stronger, which leads to the shoulder becoming bigger, and the other is the shoulder fat accumulation.

For girls, the possibility of the first one is too small. Be careful not to be frightened by the female athletes of the national team. Their exercise intensity is far beyond your imagination. Even so, in order to achieve the effect, they need to take various sports supplements, muscle powder and so on. Their body beauty is not their goal, but the result is! So in the end, they all have shoulders and legs that look stronger. But you won't, you are a lover, even if a beautiful figure is not your pursuit, but the super performance is different! So you won't get a lot of exercise, and you won't eat a lot of tonics and muscle powder for it. Therefore, it is impossible to widen the shoulders because of muscle growth.

But there is a second possibility. Enthusiasts in particular may not be able to persist. They may swim for a while, but due to other factors, they stop completely. This is a bad habit, because a lot of exercise, the body's energy intake and consumption form a balance, but once the exercise stops, the intake will not drop, but the consumption will come down immediately. This process is the process of weight rebound, which is easy to form fat accumulation on the shoulders and abdomen, and then looks wider. But this process-the accumulation of fat, is still mainly in the abdomen, and the changes in the shoulders will be much less.

So as long as you don't exercise much and don't overeat, the problems you are worried about are basically impossible!

Let's swim!
