I also liked Sculpt Sweatfest. It is a good functional fitness workout. Tracey incorporates a lot of balance work in this which really makes you turn on your core. I don't use it as much as I'd like to since I prefer heavy lifting workouts but I really enjoyed it and wish I would do it more often. Section one can be done without any equipment and section two uses a Bosu, Stability Ball, free weights and a medicine ball.
