Cardio kickboxing is a ton of fun! I loved it, but I've only taken one class. The class is 3 times a week at my gym, but I can only take it Friday night because I'm working the other times. But I highly recommend it because its a full body strength/cardio workout. In my class, and I think in most classes, you finish with abs, push ups, stretching, stuff like that so you're getting a little flexibility work too. You're really getting a lot of bang for your 45-60 minute buck!
Good luck, let me know what you think if you go! And now, a cardio carrot...just for motivation
