Other than her poor grammar in a couple of places, this is the best workout DVD I've ever used. She doesn't go too fast (which can injure you!) and it's very clear how to do the exercises. They are also effective. If you're new to working out, just do one a day, alternating days. If you're used to exercising, as I am, do all 3 in the set. There are 3 fifteen minute workouts for each area (Arms & Abs or Lower Body). This is great for novices and those that just want to stay fit.
