I really enjoy the Wave. It includes 3 DVD's one of which is more of an instructional video. The Rock it Off DVD was more challenging and had me sweating by the end. It would be great if there were more DVD's to the The Wave with. I love how you have to use your core to balance and there are some creative moves that the instructors use as well. I recommend for sure. It's fun and a great work out at the same time.
