The terms behind every good plan, explained in plain language — the same concepts the seto app uses to build and adjust your training.
RPE — Rate of Perceived Exertion — is a 1–10 score for how hard a set actually was. It lets a plan adapt to your day instead of pretending every day is the same.
Your e1RM is what a hard set says your single-rep maximum would be right now. It turns every workout into a strength measurement — without ever loading a true max.
Muscles adapt to what they are asked to do — then stop. Progressive overload is the practice of asking slightly more over time, and it is the single non-negotiable behind every result.
Tempo prescriptions like 3-1-1-0 look cryptic and are read in one breath: seconds down, pause, seconds up, pause. They exist because how fast you move the weight changes what the set trains.
A deload is a planned easy week. It is not lost progress — it is when the progress you already built becomes visible, because accumulated fatigue stops masking it.
