It starts out great, but the music option does not work as it is supposed too. The music buttons are located right by the home button, if you accidentally hit the home button, you workout starts over...grrrrrrr. I you can not skip workouts either, because it erased my progress I kept running using their timing routines, but I could not go any farther than the 1st week. Grrrrrrrr
