You say
I am a 32yo male, 178cm, 80kg, active 4 times a week. I want to cut. Give me a macro target and a chest workout using the wger database.
Your agent does
TDEE: 2750 kcal. Target: 2350 kcal (400 kcal deficit). Macros: 160g Protein, 72g Fat, 265g Carbs.
Chest Workout (wger ID 11):
- Bench Press: 3x8-10 (ID: 192)
- Incline DB Press: 3x10-12 (ID: 145)
- Chest Fly: 3x15 (ID: 102) Volume: 9 sets. Daily protein target met at 2g/kg.

About this skill
The problem
Building effective fitness plans is tedious. Calculating precise TDEE, matching macro ratios to body weight, and sourcing valid exercises from fragmented databases often results in generic or inaccurate advice.
What it does
- Calculates BMR and TDEE using Mifflin-St Jeor formulas with specific activity multipliers.
- Sets protein, fat, and carb targets based on body weight (g/kg) and specific goals like hypertrophy or fat loss.
- Queries the wger exercise database to build training splits based on muscle IDs and equipment.
- Searches the USDA FoodData Central API to provide real nutritional values and meal suggestions.
- Balances weekly set volume to ensure muscle groups stay within the 10 to 20 set growth range.
Frameworks & tools
wger API, USDA FoodData Central API, and curl.
Why this beats prompting it yourself
Most LLMs hallucinate nutritional data or suggest exercises that don't exist. This skill forces the agent to use validated math and live database queries, ensuring caloric targets and exercise instructions are grounded in real data.
Use cases
- Generating a 4 day push-pull-legs split for a 90kg male aiming for hypertrophy.
- Calculating a 400 calorie deficit plan with high protein macros for fat loss.
- Finding the exact macro breakdown of 200g of Greek yogurt and matching it to a daily target.
- Creating a workout plan limited to specific equipment by filtering wger exercise IDs.
