What each version requires
| Version | Photo rule |
|---|---|
| 75 Hard | One photo every day, all 75 days. Missing it restarts the challenge. |
| 75 Soft | Not in the original rules. The widely shared variant asks for day 1 and day 75 only. |
| 75 Medium | Daily photo, counted as one of the six tasks. |
It is a completion rule, not a vanity metric
The photo is the cheapest task on the list — ten seconds — and on 75 Hard it carries the same weight as a 45-minute workout: forget it and you start over. That is deliberate. A rule that takes no effort and no time isolates the variable the program cares about, which is whether you do the thing you said you would do on a day when nobody is watching.
It also produces the only honest record you will have. Over eleven weeks the scale moves for reasons that have nothing to do with progress, the mirror recalibrates daily, and memory is useless. Two photos eleven weeks apart are not.
Taking photos that are actually comparable
Most people's day-75 comparison is ruined by variables they never controlled. Fix them once, on day one, and every photo afterwards is usable:
- Same place, same light. Daylight from the same window beats a bathroom bulb. Avoid overhead light — it invents shadows that read as definition on one day and disappear the next.
- Same time of day. Morning, before eating, is the most repeatable state your body has.
- Same clothes. Something fitted you can wear for eleven weeks.
- Same camera position. Phone propped at chest height on a fixed surface, marked with tape if you can. Handheld from a different distance each day changes your apparent size more than 75 days of training will.
- Same angles, every time. Front, side, back. Three shots, ten seconds.
Do not review daily. Take the photo and close the app. Day-to-day differences are water, food, light and posture — nothing else — and reading them as progress or failure is the fastest way to make this the worst rule on the list. Compare at day 25, day 50 and day 75.
Privacy
Nothing in any version requires posting these anywhere. The default is a private album, and it is worth setting that up properly: a locked or hidden album on your phone, excluded from shared libraries and automatic backups you have not thought about. People share day-1-to-day-75 comparisons because they want to, not because a rule says to.
When to skip this rule entirely
A daily photograph of your own body, taken for the purpose of assessing it, is not a neutral act for everyone. If you have struggled with body image or disordered eating, this rule can do real harm while the rest of the challenge does you good.
You have options, and using one is not failing:
- Take the day-one photo, then hide the album and do not open it until day 75.
- Replace the photo with a different daily marker — a tape measure, a training log, a single line in a notebook about how the day went.
- Run 75 Soft's original version, which does not ask for photos at all.
No rule invented on the internet outranks your relationship with your own body. If this one is going badly, drop it and keep the other four.
