Today's weights should match today's body.
Four taps before you start — how you slept, how stressed you are, how motivated you feel, whether anything hurts. The session in front of you is then rebuilt around that answer, and every changed number tells you why it changed.
A check-in you'll actually do
Four sliders, about ten seconds. No chest strap, no overnight tracking, no subscription to another device — just the things that genuinely move what you can lift today.
- Sleep, stress, motivation and pain
- Skip it and the session runs as planned
- Wearable data is used too, when you have it connected
The session changes, not just a warning
A bad night does not mean a red banner and the same workout underneath. Working weights move, set counts move, and the hardest exercise can be swapped for something that still counts.
- Working loads shifted up or down per exercise
- Volume trimmed rather than the session abandoned
- Painful areas routed around, not simply skipped
Every adjustment explains itself
Anything technical carries a small (i). Tap it and you get one plain paragraph — why the number moved, what it is protecting, what happens if you ignore it — in your own language.
- Plain-language explainers on every adjusted number
- Translated into all 24 supported languages
- Override any suggestion and train your own way
It learns what a hard day looks like for you
Your logged sets are compared with what you said before them, so the adjustment gets calibrated to your history rather than a generic table.
- Built from your own completed sets
- Feeds the same progression engine as normal sessions
- Rest-day recommendations when the pattern says so
