I do tae bo because I had a friend who was doing it and she told me it was fun, and somehow I got tempted and bought the billy blanks library dvd which consists of the instructional, basic, advanced and the 8 minute workout. I switch between basic and 8 minute every other day, and eventually want to get up to advanced but I still have to pause the dvd at least 3 times durring the workout to catch my breath!
but its easy and convient and fun for me.... I can do it whenever I want.. so thats the main reason..
