RE: YES
If you get CTX AND the C-Max/CK DVD's in the same purchase you get a price break.
Just a 411 - Circuit Max is probably one of my top three all time favorite workouts. The time just whizzes by, as do you, and you truly are having so much fun you forget how hard you are working. The cardio choreography is matchless, Cathe's cueing is spot-on AND wicked at the same time (wait'll she tells you "Okay, I'll leave out the monkey sounds . . . they were waitin' for 'em!"), and IMHO it is still the best total-body circuit workout she's designed - and that's saying something.
I personally like to do Circuit Max's first six cardio-resistance cycles with leg barbell squat/lunge circuits rather than the compound upper/lower body circuits with dumbbells that she and her crew do, then throw the Cardio Kicks power drills segment on at the end and then a bonus round with the barbell for legs.
Never underestimate my skill in spending your money for you. But seriously, buy early and buy often.
