VO₂ max correlates with all-cause mortality more strongly than most other fitness markers. Going from “poor” to “average” is the single biggest health investment most adults can make. Build with Zone 2 (4-5 hours/week) + 1-2 high-intensity intervals/week. Re-test every 8-12 weeks.

What it does
Estimate VO₂ max with three field tests: Cooper 12-minute run (run as far as possible in 12 min), Rockport 1-mile walk (walk as fast as you can, record final HR), or resting HR (rough). VO₂ max correlates with all-cause mortality more than most other fitness markers — going from “poor” to “average” is the single biggest health investment most adults can make.
