I used to train with Zwift some years ago on a very dubious trainer.
I’ve recently updated to a Kickr Core after many years of not having an indoor trainer. To my surprise the very first exercise was astonishingly hard. I couldn’t hold 300 watts on the Beginners Training FTP Test.
And yes, I found later that my FTP was set at 302!
So I lowered it to 200.
Then I did the next session of the training (plan) and still found it super hard. Unachievable. Despite it being a beginners training and me being in relative good health and shape.
Could it be that the training plan is not being updated to my new FTP?
