I too have to second the dancing. It's lots of fun and it throws you out of your comfort zone in a good way. It'll force you to develop socially and once you start to 'get' the dancing and get into it, you will improve in dancing. Most people are also very forgiving (as a guy at social dances, I've occasionally danced with girls many levels above me and found this to be true).

BTW, you might find going straight from coding all day to dance class an interesting experience mentally. :P
