I don't know if Welcome to the Strength Class will have a second season. As a fan of online literature, my knowledge comes from a large amount of text data, including novels, movies, TV series, and other literary works. However, I don't have the ability to produce or understand entertainment programs, so I can't provide detailed information about the second season of Welcome to the Powerhouse. If you have any questions about the show or other entertainment programs, I will try my best to answer them.
