This tape was heaven sent! I didn't think I'd be able to keep up with a 50 minute tape, but within a couple days I was keeping pace. I do it 5 days a week and have noticed a tremendous improvment in my pulse rate. It's a lot of fun. If you can get beyond the class clown, (which is pretty easy to do) you can find yourself dancing your way to a fit condition with a smile on your face. I recommend this tape to anyone who, like me, never thought they could actually look forward to exercise.
