I am not so sure. My experience with the whole Ramp Test and FTP thing is a mixed bag.
I am quite capable of pushing beyond my limits at the ramp test, but find me constantly doubting if the then set FTP is not too high. I really struggle to complete many or even most workouts at the defined intensity of 100%.
…not because I am mentally not prepared or biting enough, no, just because I am so tired, my muscles are so sore after only one or a couple of workouts that I have to skip a couple of workouts, sometimes even a whole week, to regain muscle strength to go at it again.
When I lower the intensity by some 5-10% it is much better.
So, how come? Should I really push so hard at the Ramp Test?
Next time I will try the 20min test.t
