What problem does it solve? Planning workouts and tracking nutrition requires jumping between exercise databases, calorie calculators, and macro spreadsheets. This Skill consolidates exercise lookup, food nutrition search, and body-metric calculations 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, with full details including primary/secondary muscles and instructions. - Nutrition Lookup via USDA FoodData Central: Search 380,000+ foods for per-100g calories, protein, fat, and carbs, with a DEMO_KEY fallback when no API key is configured. - Offline Body Calculators: Compute BMI, TDEE (Mifflin-St Jeor), one-rep max (Epley/Brzycki/Lombardi), macro splits for cut/maintain/bulk, and body fat percentage (US Navy method) using pure stdlib Python. - Use Case: A user cutting weight asks for their TDEE at moderate activity, a 40/30/30 macro split at a 500 kcal deficit, and high-protein food options — all answered in one session. ## Quick Start Ask the assistant to calculate your TDEE and macro split for fat loss, then search for dumbbell chest exercises and the macros of chicken breast.
