Built around one known problem
Everything on this page is designed against a single fact: the new-year landmark makes people start and does nothing to make them continue. The research is clear that temporal landmarks boost goal initiation, and Strava's activity data shows the same population tapering around the second week of January. A reset that ignores that timeline is just a resolution with better branding.
So: thirty days, four rules, and the whole structure aimed at days 10 to 20 rather than at day one.
The four rules
| Slot | The rule | Its floor |
|---|---|---|
| Movement | 30–45 min, five days a week | A 15-minute walk on the other days |
| Sleep | Screens off at a fixed time; lights out 30 min later | Screens off, even if sleep is late |
| Intake | A water target, or protein at every meal — one, not both | Hit it by 6pm rather than perfectly spread |
| Not your body | Ten pages, a skill block, no scrolling before breakfast | Five minutes of it |
Four is deliberate. It is roughly the largest number of new rules most people hold through the fortnight when work resumes at full volume — and January's real opponent is not Christmas food, it is your inbox refilling.
Note the fourth slot. A reset made entirely of body rules turns January into a month of atonement for December, which is both grim and fragile. One rule pointed somewhere else keeps the month from being about shrinking.
The day 12 review
This is the part that makes it a reset rather than a resolution. Put a date in the calendar on day 12 — before the documented drop-off, not after it — and decide right now what happens on it. The answer is fixed in advance: hold the floors, change nothing else.
Why decide it in advance? Because on day 12 the decision feels like new information — “this is not working”, “I picked the wrong goal”, “I will restart properly in February”. It is not new information. It is the schedule, and everyone running a January reset hits it in the same week. A plan written on day one is worth more than a judgement made on day twelve.
Why 30 days
January is a calibration month, not a proving month. Thirty days ends on a real date you can see from the start, it crosses the drop-off with room to spare, and finishing it on 30 January puts you in a far better position to run something longer than a 75-day attempt abandoned on the 14th would.
It also produces information you cannot get any other way: by day 30 you know which of your four rules was written badly. That rule is the one you fix before running 75 Soft or another longer challenge in February — with the weather about to improve rather than about to get worse.
Timing the start
The first ordinary Tuesday beats the first of January. Day one on a hungover public holiday and day two on the last day of family visits are the two worst days of the quarter to be testing new rules — and starting a few days off the landmark separates your attempt from a crowd that will be visibly quitting around you. The challenge menu makes the same argument at more length, with the other options if 30 days feels too short.
Track it where you will see it
Four rules for thirty days is 120 boxes, and the point of the grid is that an empty row is obvious by day five rather than at the end of the month. Paper on a wall beats an app you can close. The printable tracker works fine for a 30-day run — use the weekly sheet and ignore the boxes past day 30.
If December was a write-off and you want to arrive at January already moving rather than starting there, the honest answer is to not wait at all: a December challenge starts in the harder month on purpose, and the habits it builds survive January better than the ones January builds.
