I'm trying to learn how to use the PMC (or the golden cheetah equivalent). At the moment, routine consists of 2xtrainer, 1xhammerfest per week, plus some strength training. (I don't count the strength training in CTL,but I do keep track of it.). The routine has ended up in about a 5 point CTL raise per week for the last five weeks. Mental issues aside, my legs are beginning to feel a bit heavy--most of the "snap" is gone, although I still look forward to my next trainer session. So my thought is to back off for a week on the intensity. My CTL is only 42 or so, and the TSB is down in the thirties, and has been for the last two weeks. Is this the right way to read it: Even though the TSB negative is relatively low, I'm carrying relatively high level with respect to current fitness. It's therefore not a crazy idea to back off a little to get some snap back so that I can dig deeper through the next cycle. That sound right? (I know that my mileage may vary).
