That has to do with taper before a major event, and recovery after one - not training. Nobody says you should only train every fifth day!

And, there's a difference between "pooped" and "overtrained." I expect my muscles to be tired most of the time when I'm in a building phase, and I doubt it's possible to make gains without ever getting muscle fatigue. It's only when you stop making gains, or exhibit other symptoms of overtraining, that you need to look at smarter recovery.

But I agree - as I said before - it's impossible to come up with a training plan without identifying what you're training for.
