This problem should be considered from both oneself and underwear. If your breasts are too big, I don't recommend wearing a sports bra. If your breasts are small but strong, you can wear a sports bra. Most of the others are considered as follows.

Quality of sports bra

In addition to its own reasons, the quality of sports bras also has great factors. If you use a sports bra with poor material, it may also increase the possibility of breast sagging. So I think it's better to buy underwear. (after all, it is better to wear it. ) This will greatly reduce the chance of sagging breasts due to this problem. Never buy an unknown brand. If you really don't know, Baidu search? See which one suits you.

2. Self-reasons

There are two reasons of their own.

Oversized chest

If the chest is too big, it is best not to wear a sports bra. Because I don't think sports bra can guarantee the stability of your breasts, I think it's better not to wear a sports bra if your breasts are too big. Because if you wear it, it will not only lead to sagging breasts, but even the sports bra on the back of your chest is too tightly clamped, and you will feel pain. So try not to wear a sports bra (just exercise at home). If we have to wear sports bras, please don't wear them too often.

Medium chest circumference

If the bust size is moderate, the chest is strong. Then you can consider wearing a sports bra. Because in this way, the sports bra can tightly wrap his chest and feel no pain. But we should pay attention to prevent the chest from expanding, which will lead to more trouble.

From the above, we can see that sports bra is not the decisive factor, but the size of your chest determines whether you can wear sports bra or not.
