Hello. I did this class on our cruise in 2002. It was just a cardio based class that included abs at the end. If you have every been to a Body Combat/Attack class or a cardio kick box class, it is the same concept. No mitts, pads or any contact is involved. Just "air" punches and kicks. I just couldn't get over how small the cardio room was! There wasn't tons of room for any side to side movement or side kicks...which made it kinda fun trying to avoid kicking the person next to you. All in all it was fun, and a good workout, but I am not sure it is worth the $10 price tag it comes with now.
In 2002, I signed up for the classes the same time I made my spa ressies upon boarding. There is a limited amount of people who can attend (8 is sounding about right), and they had a cancellation list as well, so if you want to try and if they still do sign up at that time, do it then. I believe it was a 45 minute class or so...give or take 5 minutes....
