SSB should not feel extremely easy. No workout really other than recovery week should feel extremely easy. Hell, I’m doing Traditional Base at the moment and never did I feel it was extremely easy. Boring, monotonous sure, but not easy. What does that all mean, well, your FTP is set too low. This is likely because you didn’t test well. Workouts should feel challenging, sometimes very much so and you should “fail” or have to alter workouts occasionally if your FTP is set correctly. If workouts are extremely easy you’re doing recovery rides and not improving your fitness.
I’m guessing you haven’t learned how do push yourself in a FTP ramp test. I did a ramp test today and reached a new max HR. That was after reaching new max HRs in my past two ramp tests. I was gutted and smashed after the ramp test. I literally couldn’t have pushed any further. Did you feel that way?
So you have a few options:
*retake the ramp test and go all in!
*manually adjust your FTP by 10%
*raise the intensity factor of each workout until at the end of each workout you gave a hard effort (relative to what the workout description says)
If after a week the workouts are still easy, keep raising your FTP or the intensity factor.
