You'd better not. I used to wear a silver necklace. The nature of silver is sensitive, especially soapy water, which is a little corrosive to necklaces, as well as sweating frequently. After a long time, the necklace will turn black easily, and it will not look good. Moreover, if it is washed in the necklace shop, it still cannot be restored to its original appearance. I suggest you take it off during exercise and bathing. There is no way. A little trouble is better than a black necklace.
