wger OpenClaw Fitness Skill

Manage gym routines, log workouts, track nutrition, update goals, and generate fitness reports via the wger API integrated with OpenClaw automation.

wger Fitness Manager

wger is an open-source fitness tracker with REST API for routines, logs, nutrition, and progress. This skill handles API interactions for seamless integration with OpenClaw (exec/curl for calls, subagents for analysis).

Setup (One-Time)

• API Base: https://wger.de/api/v2/ (or self-hosted URL).
• Auth: Token from wger dashboard (User > API). Set env WGER_TOKEN=your_key or pass in commands.
• Test: exec curl -H "Authorization: Token $WGER_TOKEN" https://wger.de/api/v2/workout/ (lists routines).

Core Workflows

1. View Routines & Plans

Load current workouts/logs.

Example:

• List routines: exec curl -H "Authorization: Token $WGER_TOKEN" "https://wger.de/api/v2/workout/?format=json&limit=5"
• Get log: exec curl -H "Authorization: Token $WGER_TOKEN" "https://wger.de/api/v2/workoutlog/?workout=[ID]&format=json"
• Analyze: Subagent parses JSON (reps/weight trends), ties to goals (e.g., "Squat progress +10lbs—good for stamina").

Action: Use read tool on scripts/view_logs.py for formatted output.

2. Edit/Create Workouts

Add/update routines/logs.

Example:

• Create log: exec curl -X POST -H "Authorization: Token $WGER_TOKEN" -H "Content-Type: application/json" -d '{"date": "2026-04-15", "workout": [ID], "exercises": [{"reps": 10, "weight": 135, "exercise": [SQUAT_ID]}]}' https://wger.de/api/v2/workoutlog/
• Update routine: exec curl -X PATCH -H "Authorization: Token $WGER_TOKEN" -H "Content-Type: application/json" -d '{"name": "Updated Cyber Grind"}' https://wger.de/api/v2/workout/[ID]/

Action: Run scripts/create_log.py or edit_log.py with params (date, exercise, reps).

3. Nutrition & Goals

Track meals, set targets.

Example:

• Log meal: exec curl -X POST -H "Authorization: Token $WGER_TOKEN" -d '{"date": "2026-04-15", "meal": [ID], "nutritional_values": {"calories": 500, "protein": 30}}' https://wger.de/api/v2/nutritionlog/
• View goals: exec curl -H "Authorization: Token $WGER_TOKEN" https://wger.de/api/v2/weight/

Action: Use references/nutrition.md for macros; scripts/set_goal.py for updates.

4. Reports & Analysis

Generate progress, export.

Example:

• Progress report: exec python scripts/generate_report.py --period week --output pdf (uses API for data, matplotlib for charts).
• Cron Integration: In subagents, pull data, analyze (e.g., "Adherence 80%—suggest HIIT for JITA").

Bundled Resources

• scripts/view_logs.py: Fetch and format logs (JSON to readable).
• scripts/create_log.py: POST new workout entry (params: date, routine_id, exercises).
• references/api_endpoints.md: Full wger API ref (routines, logs, nutrition).
• assets/progress_template.html: Basic chart template for reports.

When to Use

Trigger on: "Log my workout", "View wger routine", "Update fitness plan", "wger API call", "Fitness progress report". For automation: Crons/subagents (e.g., daily pull to health.md).

Security: Token in env; self-host for privacy (Docker setup in references/selfhost.md). Rate: 100/min—fine for pulls.
