If you are wanting to add some variety to your treadmill exercise then this 2002 release may be your answer. Following a four minute warm up you will turn it up for the main 35 minutes of aerobic challenge. Follow one of the five participants, who matches your fitness level, as you change speed, incline, and intensity. Intervals are the name of the game here, so whether you are a beginner, and choose to walk, or are running at a pace over 10 mph, your heart rate is bound to climb. This tape ends with a two minute cool down before leading into 9 minutes of stretching. Order your own copy of this tape by searching for the title at Collage Video.com.
