Hey there, I just purchased the 16 week Big Mountain program and I have a couple of zone 2 questions that I couldn’t find answers to:
For Zone 2 workouts in general:
When using a treadmill or stair master for zone 2 workouts, should the speed/incline be reduced in order to stay below my AeT and to compensate for cardiac drift?
16 week HR-based Big Mountain programming specifically:
The zone 2 workouts have the active portions of the workout in Zone 3: Aerobic. Although the prescribed upper limit is well below my previously determined AnT, it is also well (18 bpm) above my AeT. Is this too allow for the cardiac drift in my first question?
I guess I’ve always thought that AeT was the upper limit for a Zone 2 workout, is that wrong?
Thanks for setting me straight!
