Hello brain trust!
First time poster and newbie to training with metrics. I bought a sports watch and got a lab test for running which says my VT2 is 167 BPM with a threshold range of 167-177 BPM.
The 80/20 book suggests that 167-170 is in zone Y and to be avoided:
Z3 = 159-167
ZY = 167-170
Z4 = 170-175
So I have a lab test suggesting I work in this zone and the book says to avoid it. It’s only 3 BPM of variance.
I’m a simple beast and a bit confused. Can anyone help? Thanks in advance.
Zone Y is not as problematic as Zone X. Zone X really should be avoided for most of training, but we added Zone Y to encourage athletes to commit. It’s part of our philosophy of polarization of high intensity. We think that you should commit to either longer periods of Zone 3 (5-12 minutes) or much shorter but harder periods of Zone 4 and 5. So, Zone Y is not bad, it’s really good. Just not as good as deciding to use the other zones.
