It works by starting you out with walking and short running intervals in between, and gradually you decrease the walking intervals and increase the running intervals.
I give it 10 stars! Now, does anyone know of a similar app for weight training? I would love apps like this for different types of exercise to build up my arms, legs etc.
Oh, I should also mention that it works with the Nike + app as well ( not in conjunction, but you can run both apps at the same time) that way, you can still log your miles for any Nike challenges you have going online.
I know several of you mentioned buying this app after my last blog about it, did you guys all love it as well?
