I just want to second CrossFit as the way to go. I started in December based on AS's recommendation and I fuching love it. I have worked on in a gym for years by myself with my headphones and it got monotonous.
CrossFit is totally different. It's very sociable and the workouts are different everyday. Other members encourage you to be better. I can already notice the muscles building in my legs that I would not do in the gym because I didn't like working on legs. Now I am forced to and loving the results.
It is a little pricey but is definitely worth it if you can swing it.
