This video shows the best-selling iWorkout Muse app for the iPhone and iPod Touch that allows you to build your own custom interval training workouts mixed to your favorite music.
You’ll hear “Man in the Mirror” by Michael Jackson play to a 20-10 interval where the music only plays during the work period and stops during the rest period. However, in this workout, they do push-ups during the rest period!
