I love Cathe, so I chose Cathe. Although lately I have been doing all my new workouts (Amy Bento, Tracey Staehle, Jari Love and Kelly Coffey-Meyer). I am very much enjoying the variety. I think it's because I needed something new and the new Cathe's weren't coming, so I went elsewhere. Don't get me wrong, I can't wait to get the new workouts, but I am thrilled with the new workouts I have added to my collection. I think they will all work very nicely together in a rotation when I get the new Cathe's.
I also have and enjoy P90X. I like Tony and the workouts are wonderful. I will do another rotation probably near the beginning of next year. More into endurance and cardio right now.
