Lorrie, do I REALLY need to answer this question! LOL I think you know MY answer!!!
iTrain all the way.
I just like the variety of the workouts, first off. There are just SO many, and I REALLY like the idea that they offer new workouts each month.
I also like being given the guidelines of numbers and of different levels (walking, jogging and running). I've ALWAYS had trouble gauging my workouts using the perceived exertion checks. Yes, I know when I'm at a 0 and at a 10! That's quite obvious, but even during an iTread, when Grace says "you should be working around 5 or 6", I can never tell! LOL
Also, (and this is the competitor in me), I like to really CHALLENGE the numbers I'm given. For instance, I usually follow the runner's nubmers, but I like to push the envelope and go beyond them at some points.
What actually got me started was the cost...not expensive at all!
Enough reasons? lol

p.s. I WILL say that I do like the Cardio Coach Press Play workout. SHHHHHHHHHHHHHHHHHHHHHH
