06 — How it works
Built for you.Rebuilt from you.
01
Tell CENTUM about your life.
A structured intake: goals, schedule, equipment, injuries, how you eat. It asks what you actually have, not what an ideal week looks like.
Goals, schedule, equipment and food. Built around your real life.
02
Receive your plan.
Your whole 100 days is generated before you train once. Every session and every macro target, built for your starting point.
03
Follow today's actions.
Open the app and do what today needs. Log it, and every week the check-in rebuilds the days ahead around what actually happened.
07 — The coach
Your coachknows what you’ve done.
Every log, already read.
08 — The 100 days
Who will you bein the next 100 days?
Day 0
Tell CENTUM about your life.
Goals, schedule, equipment, injuries, how you eat. Your entire 100 days is built from it before you train once.
Day 25
The first milestone locks in.
Twenty-five days of work becomes a permanent achievement. It stays yours whatever happens next.
Day 50
Halfway, and it shows.
Your metrics now have enough history to compare against day 1: sessions logged, strength, body composition, consistency.
Day 75
Training, nutrition and recovery line up.
The last quarter is where the compounding shows. By now the plan fits you better than the one you started with.
Day 100
You did not change in one day.
You changed by completing them. The round closes, the achievements are permanent, and the decision you made on day 0 is the only one that mattered.
10 — Questions
Asked and answered.
Everything else is answered by your coach once you're in. It's on call around the clock.
Pricing is still to be confirmed. Everything is included: your full program, weekly coach check-ins, tracking, wearable sync, teams and achievements. Waitlist members hear first.
You miss them. Streaks break, that's what makes them streaks. Your plan doesn't fall apart though: at your next weekly check-in your coach rebuilds the days ahead around what actually happened, missed days included. And your achievements are permanent no matter what.
No. The intake asks what you've got, a full gym, a pair of dumbbells, or nothing, and your program is built for exactly that. Change setups mid-round and your coach adjusts at the next check-in.
Both. Your program is generated from your intake, so a first-timer and a fifth-year lifter get completely different 100 days. There's no one-size template underneath.
iPhone and Android coming soon. Apple Health, WHOOP, Garmin, Oura, Fitbit and Google Fit all connect.
As much as you told it you have. Intake asks how many days a week you can train and how long each session can run, and the program is built inside those limits, not around an ideal week you don't have.
Update your details and your next weekly check-in rebuilds around the new constraints. A change of job, gym or season is an input, not a reason to start over.
No. Apple Health, WHOOP, Garmin, Oura, Fitbit and Google Fit connect if you have them, and that data sharpens each check-in. Without one, your check-ins run on what you log in the app.
The round closes and your achievements are permanent. They stay yours even if you never open the app again. We’ll share what comes next closer to launch.
No. Centum builds training and nutrition programs, not medical advice, and it doesn't diagnose or treat anything. If you have an injury or a health condition, talk to your doctor before you start. See the health disclaimer for the full boundary.
Same 100 days.Together.
Do a challenge with friends, family or co-workers. A leaderboard that means something, because everyone on it is inside the same 100 days.
