Hi again everyone!
Time for another update. I can now go almost 140 days without a repeat if I choose. There were three major additions since the last time I updated this thread:
Firm Express: This is a 16-workout set. I have ordered it but it has not yet arrived. I am anticipating trying a full rotation with it.
Yoga Zone: 2 20-minute workouts per disk. I have 6 of them (so, 12 workouts) but there were others available that I did not get as I had plenty for my yoga needs by that point. You could easily get more workout days out of this if yoga is your thing!
Sharon Mann's The Works: I spent two days painstakingly ripping this 3-disk set onto my computer, and this gave Sharon new life for me! Most of the sections (aside from the warm-up and cool-down ones) were almost exactly ten minutes. I listed this in my planner as a 6-day rotation (strength, floor cardio, step cardio, pilates, yoga and mix) but the actual number of 10-minute sections I got off these disks was 47, so you could go almost 25 days without repeating if you did two a day. However, some categories were very much better represented than others, so I would not recommend such a rotation unless you really like high-impact cardio
I have added the Chris Freytag to my wishlist. Collage didn't have it yet when I looked, so I'll probably toss it into my next Amazon order.
