I think just getting up off the couch and moving around helps. One thing I do is constantly clean the house. I'm a neat freak LOL! I'm trying to put brisk walking back into my routine but my knees I think are getting arthritis really bad in them and sometimes it hurts to do that. I did go look at bikes today though. Found a nice one I'll have to put it on Layaway though. I hope you had fun playing ping pong at work! :)
