Your rotation is excellent, Susan! I must confess, I never stick with a series for weeks on end. Perhaps I will at some point but I have been alternating them. I do something different each week, monkey-minded me!
Remember, you had suggested I stay heavy indefinitely? I have! I am intent on staying heavy through February. I might insert a relatively short endurance rotation and get right back to heavy work because I love it! (I'll chose from among Boot Camp, Cardio&Weights, Terminator, BodyMax and SJP with ME, PH and MIS.)
Between the PS, the Pyramids and SH, I am seeing wonderful strength gains . I am a bit disappointed that I am not bulkier but I am realistic enough to know that my bod can't do it. I am not giving up. Just adjusting my expectations. My lower body strength is great. I can start out at 40 as my lowest weight on PLB and I am to up that really soon. 50 is my max weight but I feel very comfortable with it and I think I can go higher but not too much higher, for safety's sake. I am hoping I can heft sixty pounds onto my shoulders before it's said and done.
I have been going pound for pound with Cathe and that's fine with each series except PS where I am a bit lower on upper body. Not much but my 20's will remain dusty for awhile.

When I did SH three weeks ago, I was so sore I could barely move! I am really adapting well now and getting only that pleasant soreness that passes in 24 hours.
My last two weeks looked like this:
Mon TS 4 Cardio & SH CBP (I could not believe how sore my SHOULDERS got with this!)
Tues Step Blast
Wed BB Legs & Glutes (not a heavy really but I had never done it)
Thurs BB KPC
Fri PS CST/BBA
Sat Yoga
Sun Rest
Mon Clean
Tues PLB & SB
Wed PUB & KPC
Thurs Skip (Yoga/Abs)
Fri PLB & 8 Imax Intervals
Sat Rest
Sun PUB & Step Works (This was Saturdays workout but I rolled it over)
I am going into SH in the upcoming week and doing CTX Cardio on the same days. I have increased my cardio but I am going to shorten again it because it's hard to do long, high intensity workouts along with heavy strength. I am also tacking on extra work for shoulders and triceps; 1 extra workout. They are my weak points. I am doing abs twice per week with yoga (every third workout) although I skipped this week. I am doing this awful insomnia thing and it's affecting me badly. I definitely need to increase my flexibilty. I am losing it, big time. But I prefered skipping flexibility work over strength. (I should not have skipped! I didn't feel any better for having not worked out.)
I am also adding a CTX UBS/LL workout followed by PP at maximum weight as a second strength session. The following week I am Pyramiding and PPing again at max. weight. I have planned to sort of segue into the endurance workouts for March and I am tapering heavy into moderate for the last two weeks of Feb, starting the week heavy and ending more moderate. With PS and SH, I lift 1 timer per body part per week whereas, with the Pyramids I can get in two.
I have gotten quite firm with good definiton even if my shoulders are smaller than I'd like. I am strong as an ox! I've dropped a size in my pants too. In March, when I kick the cardio into high gear I hope my belly really shapes up but I must say it's not too bad at this point. Smaller but still well-insulated, LOL!
I really like this work. I think being a hardgainer, it's where my emphasis should stay. Of course, I do like lots of change so I will definitely enjoy switching off into the moderate workouts but probably only for 4 weeks or so before hitting the heavy work again for a longer duration.
Also, I prefer doing cardio and strength on the same day. More bang for my buck.

Initially, I had planned interchanging weeks of doing them the same day with weeks of alternating them but I changed the alternating weeks to same day. I have been doing strength first in hope that depleting glycogen in my muscles, will get into that lovely stomach fat storage unit I own! This seems to make sense, particularly in regard to the lower body which gets the most use in cardio. Upper body can go either way but I do enjoy getting it done first since it's the harder of the two for me.
I hope this isn't way more than you wanted to know! :
