I have just started the 6 week beginner FTP builder after completing the FTP test.
I am finding the workouts very hard, which I was expecting but I have just done week2 foundation which says that it is Endurance Zone 2. This I guess should be at moderate effort. I still found this pretty tough and my heart rate was at 160+ for the zone 2 sections and about 135 for the recovery sections. My resting heart rate is around 55 not sure what my max is but I think it would be around 180 as I am 43 years old.
I’m worried that if my heart rate is so high that I will be over training. What should my heart rate be during these zones?
