What is nabo boxing?

As an AI language model, I do not have information about "nabo boxing" specifically due to a lack of context. However, "nabo" in Danish means neighbor, so there could be a possibility that this is referring to a type of boxing or fitness program based in Denmark. It's also possible that "nabo boxing" is a term used to describe a specific style or technique of boxing. Without context, it's difficult to provide more information.
