Anyone have feedback on how VO2 max intervals should feel?
I finished the half distance low volume base plan last week and I’d been upping my FTP throughout base as I kept being able to complete the workouts fairly easily. The long SS intervals are normally medium hard, but doable, however I rarely feel like I am panting or breathing hard on the bike.
The last 4 weeks of base did have VO2 max Intervals, but I always feel like muscle fatigue knocks me out before any sort of breathing or HR limitation. Am I doing something wrong or is muscle fatigue limitations without feeling like I am dieing for air an indicator of hitting my V02 max?
