SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill helps you plan training and manage nutrition by turning exercise and food data into concrete numbers like macros, calories, BMI, TDEE, and one-rep max estimates.

Core Features & Use Cases

  • Exercise discovery via wger: Search and filter 690+ exercises by muscle, equipment, or category, then pull exercise details (names, muscles, equipment, and descriptions).
  • Nutrition lookup via USDA FoodData Central: Look up macros and calories for 380,000+ foods, supporting a free DEMO_KEY and higher limits via USDA_API_KEY.
  • Offline calculators (stdlib Python): Compute BMI, TDEE (Mifflin-St Jeor), estimated 1RM, macro splits for cutting/maintenance/bulking, and body fat % (US Navy method).

Quick Start

Ask: "Search exercises for 'lat pulldown' and estimate my BMI, TDEE, and macro targets for a cutting phase."

Frequently Asked Questions about fitness-nutrition

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

FAQPage Schema
How do I calculate TDEE and macro splits for a cutting phase?▼

To calculate TDEE and macro splits, this Skill uses the Mifflin-St Jeor equation for offline body metrics and applies phase-specific ratios for cutting, maintenance, or bulking targets. You receive precise daily caloric needs and protein, carb, and fat distributions.

How can I look up nutrition macros and calories for specific foods?▼

You can look up nutrition macros by querying the USDA FoodData Central database, which covers 380,000+ foods. The Skill retrieves per-100g nutrient data for meal planning and supports both a free DEMO_KEY and a custom USDA_API_KEY for higher rate limits.

What's the best way to find exercises by muscle group or available equipment?▼

Finding exercises by muscle group or equipment is handled via the wger API, which allows you to search and filter 690+ exercises. You retrieve detailed exercise names, targeted muscles, required equipment, and English descriptions for workout planning.

Can I estimate my one-rep max and body fat percentage without online tools?▼

Yes, you can estimate your one-rep max and body fat percentage using the Skill's offline stdlib Python calculators. It computes 1RM estimates and applies the US Navy method for body fat estimation without requiring external network calls.

Do I need a USDA API key to use the nutrition tracking features?▼

You do not need a USDA API key to start nutrition tracking because the Skill supports a free DEMO_KEY for basic USDA FoodData Central queries. Providing a custom USDA_API_KEY is optional and only necessary to bypass default rate limits.
