Windsurfing. I've tried many sports seriously - soccer, tennis, mountain skiing, still do bicycling. Nothing beats windsurfing however, not even close. After sailing for two hours in rough conditions you feel like you did P90X for two hours. But it's a lot more fun. It's not a cheap sport to start, but it's totally affordable if you're a programmer. If you live around SF, it has some of the most consistent wind - both in the (safe) bay and out at sea.
