Hey @Trout!
I not seeing that FTP decrease you are talking about. I see a 2 watt increase instead. Maybe because you applied a plan today?
However, since you mentioned that you added more volume and more intensity, have you tried tried lowering your Training Approach from Demanding to say Balanced, or lowering your weekly training load? Nate goes over different reasons as to why your FTP may be going down here.
Raising volume + intensity doesn’t always = more FTP gains. Sometimes the reverse does the trick so we don’t over do it.
