How me. decides what you do — stated openly, because trust is the whole product. The short version: a research-grounded engine owns every number; the AI only writes the words.
A deterministic rules engine computes every load, rep, set, rest, and progression — never a language model. Loads autoregulate from your RIR rating after each set. Personal records are caught with e1RM estimation. Fatigue is tracked with a Kalman-filtered readiness model. Volume sits inside evidence-cited landmarks, and nutrition targets derive from the Mifflin-St Jeor equation. Every parameter traces to published research.
A conversational layer takes the engine's decisions and writes them in calm, plain language. It explains; it never decides. The AI never picks your weights. That split is what makes the plan trustworthy and the experience human.
Every number is auditable. Ask why bench is at 65 and the app shows its reasoning — your recent RIR, the progression step, the volume range it's working inside. What you see is exactly what the coach acts on.
