What percentage of VO2 max is Zone 2?

Zone 2 corresponds to 60–70% of VO2 max, where fat oxidation is maximized and mitochondrial adaptations are greatest. It should make up 70–80% of total training volume.

What is Zone 5 training?

Zone 5 (90–100% VO2 max) develops maximal aerobic power; high intensity with short duration (30–60 sec intervals). Use sparingly — 1–2 sessions per week maximum.
