Yuri,I have been using the beginner audio (treadmill trainer volume 1) for about 3 weeks now. I was a College Runner and got burned out on running and had not done any running for about 7 years.  I am now 32 years old and I gained weight since I stopped being highly active.  I wanted to get back into running but every time I have tried to “Just go out and run”, I only do it for a few weeks.  With your workout audio right in my head, it takes me back to the days of having a coach to help motivate me. I hope to be using the next audio in a few weeks. Thanks for such a great product!!!!
