The ARZA engine
Volume, intensity and frequency: here you see them, measure them and understand them in every session.
How much work you did in total. Every set counts, added up pattern by pattern: it's the dose of your training. Too little moves nothing; too much you can't recover from. In ARZA you see it week by week, and you notice whether you're going up, down or holding steady.
Volume is how much; intensity is how hard. It measures how close to your limit you finish each set, and that decides what you build: strength, muscle or endurance. In ARZA we sum it up in a single number, so at a glance you know whether you held back or gave it everything.
How often you come back to each pattern. That dose isn't taken all at once: it's spread across the week so every session finds you fresh. In ARZA it's how many times you touch pull, push or planche. The rhythm that holds everything else together.
Sets, holds, max holds, attempts, bands, combos and RIR — every exercise gets the right input.

Score per pattern
With your score and your free days, the app has your week ready.
What days can you train during the week?
Every set you log adjusts what comes next. You never redo anything.
How did you feel?
Once a week it asks if anything bothers you. You mark where and in which movement: today you choose whether to lower the load, and while it bothers you, the Coach won’t push you there.
ARZA doesn’t diagnose or replace a health professional. If the pain persists, see one.
