Take a set to failure when the plan wanted two or more reps in reserve, and the next set always goes down, by at least one plate step.

A smart strength program that adapts to you.
Reppex writes your program from a few questions, then keeps adjusting it to what you lift, how you recover and the days you can train. Run the session from your phone or your watch, and see the reason behind every change.
How it works
A coach on your wrist, not a logbook.
Most gym apps record what you did and leave the next session to you. Reppex is being built to write the program and adjust it from what happened.
1. The plan
It writes the program.
Answer a few questions about your goal, your experience, your equipment and the days you can train. Reppex builds the program from that, exercise by exercise.
2. The session
The watch runs the session.
The next set, the load, the rest timer and logging are all on the watch. Leave the phone in your bag, or at home. The session works with no network and syncs when you are back.
3. The adjustment
Every change comes with a reason.
When the next set changes because of the last one, you see a one-line reason and an Undo. You should know why the app did something, and be able to say no.
4. The bad day
A bad day stays a bad day.
Every session is checked before it can change your program. If it does not count, the program stays where it was, and your history shows which reason applied.
- Cut shortStopped before half the planned sets
- RushedRest below the floor on more than half the sets
- LightVolume under 80 percent of your last three sessions of that workout
- Run downThe worst answer on two or more of the four check-in questions
- InterruptedA pause over 10 minutes, or idle for more than half the session
Built in public
The rules, in numbers.
Reppex follows rules you can read. These are from the current build, and the values may change as testing goes on.
Rest is part of the set
60s/45s
A set after less rest than this on a compound lift, or on an isolation, does not count toward progression. There is a 5 second grace. Short rest is allowed. It is just not evidence.
Coming back after time off
| Days away | Return weeks | Load | Sets |
|---|---|---|---|
| Under 14 | None | 100% | 100% |
| 14 to 27 | 1 | 90% | 75% |
| 28 to 55 | 2 | 80% | 66% |
| 56 or more | 2 | 70% | 50% |
Return weeks never raise a load mid session and never move the program. You see what they will do before you accept.
