Hi, Cmayes71! If you can afford the CTX DVD by all means get it! It's an amazingly multifunctional series, where you can do mix-&-matches for extended cardio, extended strength, or extended cardio + strength sets depending on what your schedule is and what your goals are.
I personally do not do formal rotations like many Forum participants do here, so I suggest you pose another question for "CTX/PS Rotations Suggestions?" and see what you come up with. I'll bet you'll get a ton of helpful suggestions. Or - novel suggestion - just do the CTX series as produced, one complete cardio+strength segment per day, and Leaner Legs on the sixth, and then rest the seventh day, every other week, and on the alternating weeks do one CTX cardio workout and one PS workout per exercise bout, completing at least 5 workout bouts per week. How's that sound?
Good luck, and welcome!
Annette
