Stop running other people's routines - build one that works for you.

Most advice is someone else's experiment

The person who swears by ice baths has different sleep, training and stress than you. Their n=1 is not yours. Copying it is guessing with extra steps.

A pre-workout, a greens powder, a $200 sleep gadget. Each one sits on top of whatever your sleep, food and training already are, and when that base is broken none of them moves a number you can measure.

The method is boring on purpose. Fix the foundations, then test one small thing at a time and track what happens. It's written down here so you skip the trial and error.

What an n=1 system actually is

n=1 means a study with one participant. You. The point is not to track everything forever. It is to run a clean, short test, read one honest signal, and make a keep or drop call.

1. 1Pick one lever. Light, cold, caffeine timing, training. One at a time, never five at once.
2. 2Set a dose and a window. Small and recoverable, run it about two weeks so the signal is real.
3. 3Track one signal. The single thing you care about, not twenty metrics you will abandon by Thursday.
4. 4Keep or drop. If it moved the signal, it stays. If not, it goes, and your money stays in your pocket.

What you get

• The experiment template, so every test has a clear dose, window and signal
• The lever library, the highest-leverage things to test first across sleep, light, food, training and recovery
• The one-signal tracking sheet, built to show what works for you, not for an influencer
• The keep-or-drop decision rule, so you stop paying for things that never earned their place
• The foundations checklist, sleep, light, food and movement, the boring base that does most of the work
• A worked example run, filled in end to end, so your first experiment isn't guesswork
• The evidence pages, every claim sourced with the hedges left in, strong called strong and mixed called mixed

Honest questions

No. It is general principles and a method for your own testing. Talk to a professional before changing anything that touches your health.

The whole point is that you find out, honestly, with a real signal instead of hype. The system shows you how to find your levers, not mine.
