Why start one
Real proof, not just effort
Lab results and wearable readings show what actually changed in your body.
A group chat comes built in
Private challenges get their own chat to swap tips, cheer and keep each other honest.
Your routine, your way
One friend tries zone 2 cardio, another tries better sleep. Everyone races the same biomarker.
Better together
Friends, family or coworkers keep showing up because the group is counting on them.
Plan at least a month ahead so everyone has time to get a baseline test. Joining a challenge never changes who can see your health data.
