Build
back strong.
An AI builds your strength plan from a deep onboarding and adapts it every day — your time, your energy and what you'd rather avoid today. You review and approve it before it exists. Adherence beats perfection, and the system is built for that.
Your first 4-week block, free
No credit card. After that, a monthly subscription in US dollars you can cancel from the app.
The plan moves.
The block doesn't.
Tell it how much time you have, how you're feeling and what you'd rather avoid today. The session recomposes in front of you, no signup.

Most fitness apps are built for people with time: streaks to protect, feeds to scroll, calories to count, badges to earn. If you're an adult with a demanding job and a family, that model breaks the first bad week — and then it makes you feel bad about it.
REBUILD is built for the week you actually have. A clear plan, fast logging, honest weekly data, and small adjustments over time. No noise. No shame. Just the next best session.
A system, not a pep talk.
Your plan comes from your data, not a template
The AI builds your plan from your history, your equipment and your schedule. Not a magazine routine.
Change the day without breaking the plan
Swap an exercise today and get a safe, equivalent alternative. The block doesn't break. And logging a set is two or three taps, with tired hands.
Week 1 recalibrates on what you did
At week 1 the plan recalculates from what you actually did, not what you meant to do.
Every new block knows you better
Each new block comes from real execution data. The system knows more about you every month.
Your first 4 weeks.
- Week 1 · The plan calibratesIt recalculates from what you actually did.
- Weeks 2 to 4 · You executeYou log each set in two or three taps.
- End of block · Your first reportWhat you did, what progressed, what to adjust.
- Block 2 · It knows you nowBuilt from how you actually trained, not from a form. This is where the subscription starts.
The app, no makeup.
What you won't find here.
- Streaks to breakConsistency is measured weekly, not daily.
- Calorie countingTrack what supports execution. Nothing else.
- Guilt mechanics"Skipped" is a status, not a verdict.
- Gym-floor noiseSober, adult, built for the long game.
For the comeback.
For the mother of two who trains at 6 a.m., before the house wakes up.
For the former player who hasn't touched a weight in eight years and doesn't want to get hurt in week one.
For anyone coming back after a long break — postpartum, surgery, three years of work — who needs a system that survives real life, not one that demands a perfect one.
Start rebuilding.
People are already training with REBUILD. We open spots in small batches so we can be there for every start, and we'll write when it's your turn.
Four optional questions help us put each batch together.
How long since you last trained?
How many days a week can you train?
Where would you train?
How did you hear about us?
Thanks. We'll write when it's your turn.
By signing up you agree to receive occasional updates about REBUILD. Nothing else is done with your email.
How much does it cost?
The first 4 weeks are free. After that it's a monthly subscription in US dollars that you can cancel anytime from the app.
What happens if I stop paying?
Your history stays yours and you can still see it. What stops is the generation of new blocks.
Is it an iPhone or Android app?
It works on both. You install it from the browser, no app store needed.
Do I need a gym?
No. The plan is built around the equipment you have.
Does it work if I'm coming back from an injury?
The plan takes into account what you'd rather avoid, but REBUILD doesn't replace a health professional. Check with one before you start.
What does the AI do with my data?
It uses it to build and adjust your plan. The details are in the privacy policy.
