Body recomposition for desk workers
Skinny fat?Build muscle and lose fatwith habits you can stick to.
Bulking adds fat you don't want. Cutting costs muscle you don't have. Perdura plans a slow recomposition for you: what to lift next time, what to eat today, and whether it's working.

Who it's for
Thin in a shirt.
Soft without it.
Skinny fat means low muscle and stubborn fat at once, so a bulk feeds the fat and a cut eats the muscle. You don't need to lose a lot of weight. You need to change what it is made of, with three habits kept for months.
- You sit at a desk most of the day.
- Bulk-and-cut seasons don't fit your life.
- You want habits that hold for years, not a 12‑week plan.

Training
Your next workout, decided.
At the gym you see each exercise, what you lifted last time and what to aim for today. Log each set, and Perdura reads them against the rep range and gives one instruction for next time.
- Add weightEvery set reached the top of the rep range.
- Add repsYou're inside the range. Beat last time.
- Lower the weightA set fell below the range. Drop the weight and rebuild.

- Every set reached 10 reps last time, so the weight goes up one step.

Measure
- Fat or muscle?
- Just water?
- Is it working?
Stop
guessing.
The scale can't tell muscle from fat. A tape measure can, and body scans if you get them. Perdura charts fat and muscle against your first scan and draws your body from your measurements, so you see the change the mirror hides.
BodySample · 4 months
Waist: 85.5 cm, down 2.5 since the first scan. Lit on the body: waist.
Tape measurements light their part of the body. The shell is the first scan.

Ask Perdura
A guide on every page.
Perdura, the guide at the bottom right of every page, explains how Perdura works: what a number means, how it is worked out, where a setting lives. It answers from Perdura's own definitions first; a question they don't cover can go to an AI, with your question only, never your data.
- Ask about thisUnder every “How is this calculated?”, and on every exercise.
- No health adviceIt explains Perdura and never assesses pain, injury or illness.
