Three clear phases, conservative load progression, rescheduling for missed sessions, and deload logic in code.
Track weight trends, waist, sleep, resting heart rate, steps, cardio, and progress photos without shame-driven UX.
Gemma 3 27B by default, Llama 4 and Mistral fallback paths, JSON validation, and safety templates for red flags.
Workout OS is built for the long game: calmer language, clearer next actions, higher joint tolerance, and progress signals that do not collapse into scale obsession. The app never punishes missed days. It moves the plan forward and protects recovery.
