Hi Calee,
Welcome to Catheland! My first Cathe DVD was Boot Camp. It's a killer workout but it's fun and goes by so fast. There are eight fitness cycles that involve cardio, upper and lower body strength work and core work. I also love High Step Challenge and Kick, Punch and Crunch. My favorite strength training DVDs are the Gym Style Series and the Slow and Heavy series. I have seen significant definition in my upper body when I include these DVDs in my rotation. I did Gym Style Legs last night and my legs are screaming this morning.
Cathe has a great website that allows you to view her workouts and eveyone on the forum has knowledge to help you make the right choice.
