Also, the abdominal routine in Muscle Max is among my favorites in Cathe's vast array of ab / core workouts. Nothing fancy, but fewer drills with longer sets. My abs always bark at the end.
Slow and Heavy is very, very good as well. Sharona, if you can swing it financially, consider getting both so that you'll have a complete split-set series with Slow and Heavy AND a one-hour (or so) total body workout with Muscle Max.
