Well, you can mix CTX up in all sorts of ways, obviously, but to start I liked to put it in order to they weight training went in my usual order: chest, back, shoulders, bis, tris. I can't recall exactly which workouts they are each attached to, but that worked really well for me. I did it that way for about 4 weeks and even though I was only strength training each part once per week, I got amazing strength gains. After the 4 weeks, when I went back to doing MIS, I was sooooooo much stronger I couldn't believe it. But some people liked to shuffle it around to they do two body parts per day after the cardio, so they hit each one twice. I'm hoping no one does Leaner Legs (aka Meaner Legs) more than once per week. If they do, they must have legs like a racehorse.
Anyway, that was the way I shuffled mine, but to possibilities are almost limitless. That's what makes it such a fun series and great buy. Have a lot of fun with it, I think you'll absolutely love it.
