The 7 Non-Negotiables
Why this guide exists — and how to use it
Exercise improves brain function, sleep quality, insulin sensitivity, hormone balance, bone density, and mood, and reduces the risk of almost every chronic disease — if it came in a pill, it would be the most prescribed drug in history.
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 (muscle-building and training-structure science, Renaissance Periodization), Brad Schoenfeld (resistance training meta-analyses), Iñigo San Millán (low-intensity cardio and cellular energy research), 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-Negotiable | Why it matters |
|---|---|---|
| 1 | Train your VO2 max | VO2 max (a measure of how much oxygen your body can use during hard exercise) is the single strongest predictor of cardiovascular mortality. Moving from the lowest to second-lowest fitness category cuts all-cause mortality risk by ~50%. |
| 2 | Do resistance training | Skeletal muscle mass is one of the strongest independent predictors of all-cause mortality. Never stop lifting. |
| 3 | Do Zone 2 cardio | Zone 2 means a pace easy enough to hold a conversation. 150–180 min/week of it — a practical starting target within the WHO's broader 150–300 min/week range covered in Section 9 — builds mitochondrial density (the number of energy-producing structures in your muscle cells), improves insulin sensitivity, and underpins all other cardio capacity. |
| 4 | Apply progressive overload | Without consistently increasing training demand, adaptation stops. This is the non-negotiable mechanism behind all physical progress. |
| 5 | Recover properly | Sleep, nutrition, and deload weeks are not optional extras — they are when adaptation actually occurs. |
| 6 | Train for your future self | The physical capacities required at 80 — balance, grip strength, single-leg stability — must be built decades earlier. |
| 7 | Show up consistently | The best programme you do irregularly is worse than a good programme done consistently. Adherence is the first variable. |
