Coach-Prompt

Coach-Prompt is a local AI-powered strength coaching assistant. It analyzes short text descriptions of lifts and returns structured, actionable coaching feedback.

The system is designed to:

• Avoid over-coaching
• Prioritize safety
• Return machine-readable output (JSON)
• Run locally using Ollama (no paid APIs)

Coaching Output Schema (v1)

All model responses MUST follow this schema exactly.

{
  "exercise": "string",
  "assessment": {
    "overall_quality": "good | acceptable | poor",
    "confidence": 0.0
  },
  "primary_issue": "string",
  "secondary_issues": ["string"],
  "primary_cue": "string",
  "accessory_exercises": ["string"],
  "safety_notes": ["string"]
}

Key design decisions

✅ One primary cue

Prevents:

• Information overload
• ChatGPT-style rambling

✅ Confidence score

Lets you later:

• Filter low-quality responses
• Trigger fallback logic
• Log uncertainty

✅ Safety notes

Signals:

• You thought about liability
• You understand real-world use

✅ No long explanations

Forces:

• Deterministic output
• Easy API / UI integration

This is much better than “free text advice”.

Non-goals

This system does NOT:

• Diagnose injuries
• Replace a certified coach
• Analyze video or biomechanics (yet)
• Provide medical advice

Input Format

The system currently accepts:

• Exercise name (string)
• Free-text description of perceived issues

Example input: "I feel my knees cave in at the bottom and I lose tightness"
