SUN 8:00 AM · The reminder
The session and the weight, right in the notification.

A week with Rhetra
SUN 8:00AM
Push / Pull / Legs · week 12
SUN 6:34 PM · The trial
One set, one tap. It's logged.
Big targets, numbers in mono, rest that starts by itself. Leave the phone in the locker: the watch has the same set.
SUN 7:12 PM · The verdict
The record falls. It's marked in bronze.
Caught down to the set, dated, with the set it came from. And the next weight, already computed, waits for your yes.
MON 7:30 AM · The review
What's going up, what's on hold, and why.
Consistency, energy, how it felt. No made-up score: facts, and what they say about your week.
The progression engine
Every weight explains itself.
A 5×5 on the bench press, eight weeks. The weight decided, and why — misses and deload included. Tap a week.
60.0 kg
ῥήτρα — the word that is law
The engine proposes, you decide. No weight without its reason. Nothing saved without your yes. And when the data runs short, Rhetra refuses to guess rather than guess wrong.

The temple
Alone, or with your people.
Holding on for eight weeks alone takes rare discipline. Found a temple: a private group, joined by link or QR code. No directory, no strangers.

Sessions get passed around
A session you liked goes up on the wall; your adepts take it whole, progression rule included, and redo it with their own weights.

And challenges get thrown
An AMRAP, a for time, a distance, a max. Everyone takes it when they can, where they can; Divine Recognition ranks the results.
