Building your first program

Mettle needs to know your situation before it can write anything sensible. The setup is short and every answer is changeable later.

1. 01

   Goal

   Build muscle, get stronger, or general fitness. This shapes rep ranges and how volume is distributed.

2. 02

   Experience

   Answer honestly. Mettle will re-infer your real level from how you train anyway, and it will tell you when it thinks you have moved up.

3. 03

   Equipment

   Full gym, home setup, dumbbells only, bodyweight. The engine only prescribes what you can actually load.

4. 04

   Schedule

   Training days per week and roughly how long a session can be. A realistic three days beats an aspirational six.

5. 05

   Units and bodyweight

   Pounds or kilograms, and optional bodyweight, which lets Mettle judge strength relative to you rather than in the abstract.

6. 06

   Generate

   A split is chosen, exercises are selected from the curated library, and the deterministic engine composes the sets, reps, and rest.
