The music was good, it sounded mostly instrumental from what i remember. It would have a driving beat when you needed the umph, it'd be calmer between sets when you rest. Chris explained they are taking a lot of time to match it just perfectly and that is taking a long time but it sounds like it will be worth it.
Im excited to get this, but im also three months pregnant. Since we have no idea when it'll be done, i have no idea when i'll be able to start. Kinda hard to lift heavy when you have a big belly with a baby! So maybe it will be my post baby workout.
I believe it was done to a chest workout. it was a rough picture but clear music, just to give us an idea.
