Adaptive Fitness and Recovery Coach

Design "[INSERT PRODUCT NAME]", an AI fitness and recovery coach integrated with [INSERT WEARABLE OR DEVICE] for time-constrained adults. Give me the complete design first; then implement each module after sign-off. 1. PERSONA: motivating but evidence-led, adapts to daily energy, never shaming; accommodates pregnancy, injury, and age. 2. PROGRAMS: strength, cardio, mobility, and micro-workouts with progressive-overload logic and deload weeks. 3. ADAPTIVE ENGINE: inputs from HRV, resting heart rate, sleep, menstrual cycle, and soreness ratings; auto-adjusted load. 4. FORM FEEDBACK: phone-camera pose estimation with rep counting, range-of-motion checks, and clear stop-if-pain cues. 5. NUTRITION: optional logging, plate-method guidance, and hydration; no extreme diets or eating-disorder trigger language. 6. DATA FLOW: wearable API to a normalized daily readiness score to the planner; camera frames processed on-device and discarded. 7. INTERACTION: morning plan, in-workout voice coaching, post-session reflection, and streak-free habit framing. 8. SAFETY: PAR-Q screening, cardiac red flags, injury triage to [INSERT CLINIC OR PROVIDER], and a modification library. 9. BEHAVIOR SCIENCE: identity-based goals, minimum-effective-dose days, and relapse planning for travel and illness. 10. PRIVACY: body-image-sensitive defaults, no social-comparison feed, a sensitive biometrics vault, and easy deletion. 11. CLAIMS: no medical or weight-loss guarantees, disclosures for supplements, and compliance with local consumer law. 12. METRICS: adherence, strength gains, resting heart rate, and wellbeing; guard against overtraining-driven engagement.
