Adding my 0.02. These workouts are top notch!

I have a friend who used them when running outside when she was training for marathon season (on her interval days). They are really, really motivational. I keep a few of them on my ipod for when I travel and am forced to use hotel gyms - they make any piece of cardio equipment much easier to bear!

Oh, and Coach Sean is a genuinely nice guy and provides amazing customer service, too.
