This is a suspension trainer, famous for TRX. (Not TRX) This is a set including the main unit, door anchor, carabiner, and mesh bag. It is new and unused, but I am selling it at a low price, so please refrain from purchasing if you are sensitive to minor imperfections or are looking for a perfect product. My account name states that I do not accept price negotiations, but some people still try to negotiate. Also, please refrain from commenting if you do not intend to purchase. (I will block those who negotiate prices or disappear after commenting.)
