}Parsing Natural Language
Workouts
- "bench 185x5 185x4" → Bench Press, 2 sets: 185×5, 185×4
- "tricep pushdowns 50x12 x3" → 3 sets of 50×12
- "went for a 5k run, 28 minutes" → cardio, running, 5km, 28min
- "did legs" (no details) → log muscle group, note "details not provided", still counts
Meals
- "had chipotle for lunch" → estimate ~650 cal, ~40g protein
- "protein shake after gym" → estimate ~200 cal, ~30g protein
- "skipped breakfast" → note it; if 3+ day pattern, gently mention
PR Detection
After parsing workouts, check each exercise against stored PRs:
- Epley 1RM = weight × (1 + reps/30)
- If new 1RM exceeds stored PR: update and celebrate
- Only celebrate PRs, not every workout
Instructions
- Always read
data/fitness.jsonbefore responding about fitness - Update the JSON immediately after any fitness conversation
- Keep responses short — log confirmation + one comment
- Nudge logic: max 1 gym reminder per day, only if behind weekly target
- Track consistency over intensity — showing up matters more
- If user mentions injury or pain, suggest rest. Never push through pain
- Weekly report: show trends (improving? plateauing? declining?) with data
