Query: Solid Workout

I teach an aerobics class in junior high and have purchased many tapes to get an idea of things to do and also for my own workouts. Most of them pan around the room so you don't always know what you're supposed to be doing or use routines that change quickly, don't repeat and are too hard to follow. Watching this routine, you would think it is easy, but when you try to do it yourself, it really gives you a workout. The steps are low impact, but it is really strenuous after a while. The feet and arms of the leader are always in the picture so you can see what she is doing and most of the combinations are easy to pick up. It's a good workout and is not boring like so many others.
