SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill removes the guesswork from training and eating by helping you find exercises, calculate nutrition targets, and estimate body composition with fast, reliable formulas.

Core Features & Use Cases

  • Exercise discovery: Search and filter hundreds of exercises by muscle, equipment, category, or name for more effective workout planning.
  • Nutrition tracking: Look up calories and macros for foods, then translate food data into practical meal planning and portion guidance.
  • Fitness calculations: Estimate BMI, TDEE, one-rep max, macro splits, and body fat for cutting, bulking, maintenance, and performance goals.
  • Use case: A lifter can plan a chest day, estimate a lean-bulk calorie target, and check protein intake in one workflow without switching tools.

Quick Start

Ask the skill to calculate your TDEE, build macros for your goal, and suggest exercises for the muscle group you want to train.

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 macro splits for a lean bulk?

You can calculate TDEE and macro splits for bulking using built-in offline Python calculators that estimate Total Daily Energy Expenditure and divide calories into targeted protein, carbohydrate, and fat ratios.

Can I look up specific food calories and macros using the USDA database?

Yes, you can look up food calories and macros using USDA FoodData Central integration, which retrieves nutritional data to help translate food items into practical meal planning and portion guidance.

How do I find exercises by muscle group and available equipment?

You can find exercises by muscle group and equipment using the wger exercise API access, which lets you search and filter hundreds of movements by category, muscle target, or name for effective workout planning.

Do I need an internet connection to estimate body fat and BMI?

No, you do not need an internet connection to estimate body fat and BMI because the skill uses pure Python offline calculators for body composition, TDEE, and one-rep max estimations.

What's the best way to plan a full workout routine and nutrition targets together?

The best way to plan a workout routine and nutrition targets together is to use this skill's unified workflow, allowing you to find exercises via wger, calculate calorie targets, and check macro splits without switching tools.

Does this approach work for both cutting and maintenance calorie planning?

Yes, this approach works for cutting and maintenance calorie planning by estimating your TDEE and applying appropriate calorie deficits or maintenance targets alongside macro splits tailored to your specific fitness goal.
