Scott,

I have conducted a few HR drift tests and it appears my Aerobic Threshold is 140 bpm. Which means I have been training in Zone 3 a lot the last year, so I am trying to reverse that. This week I did 4.5 hours of Z2 work (132-138  bpm Average). Can I double check my zones with you?

Zone 1: 0 bpm to 125 bpm

Zone 2: 126 bpm to 140 bpm

Zone 3: 141 bpm to 160 bpm

Zone 4: 161 bpm to 190 bpm
