15 Hard,
done with your crew

Two brutal weeks. No passes, no excuses. A reset, not a lifestyle.

What it is

15 Hard is a 15-day reset: wake up by 7am, a 60-minute workout, a cold shower, no junk food, 20 pages of reading and 3 litres of water, every day, with no passes. It is short on purpose, meant as a jolt rather than a way of life.

Two weeks is long enough to prove something to yourself and short enough that a crew can carry you through it. Everyone logs on the same board, and with no passes to hide behind, a missed day is visible to everyone the same day.

Questions people ask

What are the habits in 15 Hard?

Wake up by 7am, a 60-minute workout, a cold shower, no junk food, 20 pages of reading, and 3 litres of water. All six, every day, for 15 days.

Why does 15 Hard have no passes?

The point of a two-week reset is that it is unbroken. If a day is missed, the challenge is honest about it rather than papering over it.

Is 15 days long enough to build a habit?

It is a reset and a proof of discipline, not a full habit-formation window. Many people run 15 Hard first and then move onto a longer challenge like 75 Smart.

How many people can do the challenge together?

Up to five people per crew, including you. It is kept small on purpose so everyone actually notices when someone goes quiet.

Do I need to download an app?

75 Smart is a web app. It runs in any phone browser and can be added to your home screen like a native app. There is nothing to install from an app store.

Does it cost anything?

Running a challenge with a crew is free. Custom branding, larger groups and participation reporting are paid team features.

Can my crew see my private data?

Your crew sees which habits you checked off each day and your streak. They never see notes, journal entries or anything you did not log as a habit.
