This class is working for me right now. Not much about it changes from week to week, but right now with the injury problems this class is pretty risk free, and I pretty aware of those that are there. I also like Brian (the instructor) does a great job of working every major muscle group. I am always shocked by the sweat that I get from a non-cardio class. Also, the class is a good way to get me to really focus on my abs, and the form of each of my exercises. I always place myself close to the instructor so that I can check my form easily.
