SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill helps you quickly find exercises, estimate key fitness metrics, and look up food calories and macros so you can plan training and nutrition without doing manual calculations or searching scattered sources.

Core Features & Use Cases

Exercise lookup via wger: Search or filter exercises by muscle, category, equipment, or name, then read detailed instructions and key attributes.
Nutrition lookup via USDA FoodData Central: Fetch per-100g nutrition facts for foods and detailed nutrient profiles by FDC ID, using USDA_API_KEY or DEMO_KEY.
Offline calculators (pure Python): Compute BMI, TDEE, one-rep max (1RM) estimates, macro splits, and body fat % using built-in formulas.

Quick Start

Use the skill to get a macro plan and calories for a target goal by asking: "Give me my daily TDEE and a macros split for fat loss for a 75 kg, 175 cm, 30-year-old male who is moderately active."

Frequently Asked Questions about fitness-nutrition

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I calculate my TDEE and macros split for fat loss or muscle gain?▼

To calculate your TDEE and macros split, provide your weight, height, age, gender, and activity level to compute total daily energy expenditure and target macronutrient ratios for your specific fitness goal.

Can I look up food nutrition data from USDA without an API key?▼

You can look up USDA FoodData Central nutrition facts without a personal API key by using the DEMO_KEY fallback, which retrieves per-100g nutrition data and detailed FDC ID nutrient profiles automatically.

How do I find gym exercises that target specific muscles with available equipment?▼

To find gym exercises by muscle group, filter the wger exercise database by category, equipment, or muscle name to retrieve detailed exercise instructions and key attributes.

What fitness metrics can I estimate offline without external API dependencies?▼

You can estimate BMI, TDEE, one-rep max (1RM), macro splits, and body fat percentage offline using built-in pure Python formulas that compute deterministic body metrics without external API calls.

Do I need a USDA_API_KEY to retrieve food calories and macros?▼

You do not need a USDA_API_KEY to retrieve food calories and macros; the skill uses the DEMO_KEY fallback to fetch per-100g nutrition facts and detailed nutrient profiles by FDC ID.

What's the difference between TDEE and BMR when planning a nutrition goal?▼

TDEE represents total daily energy expenditure including activity level, while BMR is the base metabolic rate at rest; the skill computes TDEE to calculate accurate macro splits for goal-oriented diets.
