Oh so many things!! She is very fun and explains her reasoning for everything. She does talk through the workout and there isn't any music. It took me awhile to get used to it, but I've come to enjoy it. It's like working out with a friend and you chat the whole time. Another thing I enjoy, is that her over 50 workouts are only 20-30 minutes. She has them divided between weight loss or body shaping so you can choose what you want to do.
