I was skeptical bc it was a dvd.....but its so great!!! In live in NY and its too cold early in the morning this time of year to go out to the gym (and evening workouts....never "workout" for me). So a dvd in my apt was the solution. Its only the first week, and Ive only done level 1 but Im sore. I typically worked out a few times a week at the gym so Im no couch potatoe. The best part is its only 20 mins and the time flies by. I plan to continue level 1 until I make it through and do every move!!! (My arms strength is a lil lacking) Once I do Ill do it another week and move to level II. As for music...I nvr noticed it, Jillian talks the whole time (which isnt much time at all), I like her though.
