Indoor gyms in multi-tenant housing
Recently I have seen some discussion about indoor gyms within multi-tenant housing (apartment buildings). Other than to have a couch portal, I personally think these satisfy the portal criteria.
My thought process is this: playgrounds within multi-tenant housing are acceptable (AMA response clarified this), indoor submissions are acceptable (AMA response clarified this), and exercise equipment (usually in outdoor parks) are acceptable. Why wouldn't indoor exercise equipment within multi-tenant housing be acceptable? They promote both a healthy lifestyle and exercise, and are a place where people gather.
