This is the first 10 Minute Solution workout I have purchased. However, I have many other workout DVDs, and the portability and option to adjust the length of the workout makes this one one of my favorites. I often use this one as an add on to my cardio workout, so that I can get some quick and simple strength training in. It is also a very good solution for strength training while traveling because the strechy band is very portable.I would not necessarily use this DVD as your primary strength training method, but it is a nice addition to any fitness library, especially if you are looking for something that is portable or that gives you the flexibility of choosing a short, medium, or long workout.In addition, the instructor is clear and motivational without being too cheery, and the moves are easy to learn.
