I could not wait to download your Volume 1 and get started.  It has given me the confidence to go above and beyond where I thought I could ever be with my running. After doing Volume 1 just a few times, after I was done, I would get back on the treadmill and run even more. Your encouraging words are just what I need to keep me motivated. I am ready to get Volume 2 and kick some butt.

In fact, doing this exercise is so fun that I actually enjoy high intensity interval training
