I am considering doing The Firm's 90 day rotation calendar. It sounds like a nice change of pace and I'd like to get more use out of my Firm tapes than I am now. But, of course, I have a few misgivings and I'd love to have input from some experienced Cathe users. Can anyone answer me this: After using the 90 day rotation calender workout Did you feel "burned out" after doing weight work so frequently? Do you think the Firm's "more weights, less aerobics" philosophy panned out as far as body shaping and fat burning are concerned? I'd like to hear from some MIS and PS series users on this. One thing that has always kind of bugged me about the Firm is the aerobics just aren't tough enough or long enough in the "Total Body" tapes and crosstrainers. I always feel a bit short changed. (Maybe it's just fear of fat creeping on due to lack of Catheing) Maybe I could integrate some Cathe tapes. I am afraid of losing the aerobic and strength gains I have sweated so hard for with the everpopular IntervalMax and MIC. Also, I hate to start at the "intermediate level" that The Firm recommends. I think I could jump into Int/Adv level. (At least I hope so.) Thanks for reading and I can't wait to hear from you "buffies" out there.
