66 days. 5 habits. Miss a day, start over.

Protocol 66 is the science-backed alternative to extreme fitness challenges. Based on habit formation research — not bro science — it takes exactly 66 days to build lasting habits.

THE RULES ARE SIMPLE

• Pick 5 daily habits
• Complete all 5 every day
• Miss a day, restart from zero
• Rest days are earned, not given

WHY 66 DAYS? Research by Phillippa Lally at University College London found it takes an average of 66 days to form automatic habits. Not 21. Not 30. Not 75.

THIS ISN'T FOR EVERYONE No streaks to protect you. No lives. No second chances. If you're looking for an app that goes easy on you, this isn't it.
