Gym at the Park video

Tripp here - Same day, same park.  Another thing many parks have is places to work out.  I don't mean just tracks or pull up bars.  They do have those.  I mean something that corresponds to most (or all) of what we have in a gym to work out.  Check this quick video out.  I've seen these things in two different parks here in Guangzhou.  I have no reason to think it is just a local thing, but I really have no idea.
