how it works

Prescribed

Autoregulated

Explained

One Decision

01

build the routine once

pick your exercises from a catalogue named the way you'd say them out loud. set your rep range and how many sets. then don't touch it again.

02

Check in before you start

One slider. Recover takes 10% off the bar and halves the volume without touching your progression. Push adds weight a session early. Steady does what the plan says.

03

Lift the numbers it gives you

Every set arrives pre-filled with a weight and a rep target, plus one sentence explaining why it changed. You never do the math.
