I love that every day is different and that every day is challenging. Since it is a fast-paced workout, my brain doesn't have enough time to think about how much I'm doing, so by the time I'm done with the workout, it is like "Wow! I just did ALL of that!" I love that it is an effective workout and you see results quickly. And my favorite part of each workout is the high-five from the coach I get on the way in the door!
