Rules Decide.
AI Explains.
Gymmie builds deterministic, auditable training plans from your equipment, readiness, recovery signals, and training history.
Deterministic Intelligence
Gymmie keeps workout decisions in versioned rules, then uses AI only to explain the plan in plain language.
Pass the right criteria. Every time.
Transparent logic. Always verifiable.
Clear explanations. No black box.
Right stimulus. Right time.
Measured, calibrated, repeatable.
Training
Guardrails.
Performance requires reliability. Gymmie uses your check-ins and training history to reduce avoidable overload before you start your workout.
Readiness Gates
Recovery, fatigue, and check-in signals constrain training before a plan is shown.
Safety Checks
Deterministic limits keep training within configured workload, fatigue, and readiness constraints.
Decision Evidence
Training Load
Fatigue Levels
Fatigue Map
Muscle fatigue evidence informs deterministic workload limits.
Rule-Backed Explanations
"Your recent load and readiness signals triggered a recovery constraint. Today's session was reduced by rule, then explained in plain language so you know exactly why."
