That 6-zone Couzens chart is a bit unusual. It looks like
Couzens usually defines 5 heart rate zones:
- Recovery (Sub AeT)
- Aerobic base (AeT - VT1)
- "Specific endurance conditioning for event" (what's wrong with calling it "tempo"?)
- Threshold (sub OBLA/VT2)
- VO2/Speed (VT2+)
His chart (
shown up-thread) included another zone called "Easy", which is what exactly? Perhaps Couzens was embarrassed by how much time his athlete was spending in zone 2, so he invented a new zone to split up the zone 2 time and make the graph look less wacky.
