Take a guess

Well, it's not exactly tai chi but I guess it does the trick. This exercise machine sits just outside the front of my apartment. I saw one lady using it the other day. She seemed to be getting a workout pulling those ropes up and down. I' m not sure what the metal disks are for in the enter of the pole. Maybe you do something with your head? Well, I may be joining them soon since getting to the park in the morning means walking through traffic jams and inhaling lots of bad fumes. I'm just practicing in the apartment parking lot for now.
