What problem does it solve? Planning workouts and tracking nutrition requires jumping between exercise databases, calorie calculators, and food label lookups. This Skill consolidates exercise search, food macro lookup, and body composition math into one workflow backed by free public APIs and offline Python calculators. ## Core Features & Use Cases - Exercise Search via wger: Query 690+ exercises by muscle group, equipment, category, or name using the wger API with no authentication required. - Nutrition Lookup via USDA FoodData Central: Retrieve calories, protein, fat, and carbs per 100g for 380,000+ foods, working instantly with DEMO_KEY or a free API key for higher rate limits. - Offline Body Calculators: Compute BMI, TDEE (Mifflin-St Jeor), one-rep max (Epley/Brzycki/Lombardi), macro splits for cutting or bulking, and body fat percentage (US Navy method) with pure stdlib Python. - Use Case: A user asks for a chest workout with dumbbells and a 500-kcal deficit meal plan. The Skill filters wger for chest exercises with dumbbell equipment, calculates the user's TDEE, and generates a macro split with per-meal gram targets. ## Quick Start Ask the agent to find dumbbell exercises for chest and calculate your TDEE and cutting macros based on your weight, height, age, and activity level.
