Fitness Tracker — Workout & Health Accountability

Tracks workouts, meals, PRs, and fitness consistency. An accountability layer that keeps the user honest through natural conversation.

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

1. Always read data/fitness.json before responding about fitness 2. Update the JSON immediately after any fitness conversation 3. Keep responses short — log confirmation + one comment 4. Nudge logic: max 1 gym reminder per day, only if behind weekly target 5. Track consistency over intensity — showing up matters more 6. If user mentions injury or pain, suggest rest. Never push through pain 7. Weekly report: show trends (improving? plateauing? declining?) with data
