The 7 Non-Negotiables

Why this guide exists — and how to use it

1 min read·Updated June 2026

This guide synthesises the best evidence-based exercise science into one complete, readable document. It draws on the work of Peter Attia (longevity medicine), Mike Israetel (hypertrophy and periodisation, Renaissance Periodization), Brad Schoenfeld (resistance training meta-analyses), Iñigo San Millán (Zone 2 and mitochondrial function), and a range of peer-reviewed literature from exercise physiology. Read it once end-to-end, then return to sections as reference.

The 7 Non-Negotiables

Of everything in this guide, these have the greatest and most consistent impact on how long and how well you live.

#Non-NegotiableWhy it matters
1Train your VO2 maxThe single strongest predictor of cardiovascular mortality. Moving from the lowest to second-lowest fitness category cuts all-cause mortality risk by ~50%.
2Do resistance trainingSkeletal muscle mass is one of the strongest independent predictors of all-cause mortality. Never stop lifting.
3Do Zone 2 cardio150–180 min/week of low-intensity sustained effort builds mitochondrial density, improves insulin sensitivity, and underpins all other cardio capacity.
4Apply progressive overloadWithout consistently increasing training demand, adaptation stops. This is the non-negotiable mechanism behind all physical progress.
5Recover properlySleep, nutrition, and deload weeks are not optional extras — they are when adaptation actually occurs.
6Train for your future selfThe physical capacities required at 80 — balance, grip strength, single-leg stability — must be built decades earlier.
7Show up consistentlyThe best programme you do irregularly is worse than a good programme done consistently. Adherence is the first variable.
