Query: One of my favorites

This dvd has become one of my favorite Firm workouts. It isn't the toughest one, so I'd classify it as more of an intermediate workout. I don't use Firm dvds for the cardio, and that's why I like this one. It tends to focus on muscle building, and it's pretty basic. You won't regret this one if you want to tone up.
