TDEE and macro split calculations are computed offline using pure-stdlib Python formulas. You provide your weight, height, age, gender, and activity level to generate personalized calorie targets alongside protein, fat, and carb splits for cutting, maintaining, or bulking.

Food nutrition lookup retrieves calories and macros per 100g from the USDA FoodData Central database. It requires an optional USDA API key but automatically falls back to the DEMO_KEY if you do not provide one, ensuring access to thousands of food entries without registration.

Exercise discovery searches over 690 approved exercises via wger English endpoints. You can query by muscle group, category, equipment, or name to retrieve exercise details suitable for building customized gym routines and workout plans.

No external package installations are required. The body composition, BMI, one-rep max, and TDEE calculators use pure-stdlib Python for deterministic results, while exercise and nutrition lookups rely on accessible web APIs with a demo key fallback.

Body fat percentage is estimated offline using body circumference measurements. The pure-stdlib Python calculators process your circumference inputs to deliver deterministic body composition results without requiring specialized clinical equipment or dual-energy X-ray absorptiometry scans.

One-rep max is estimated using offline performance calculators that take your current lifting weight and repetitions as input. These pure-stdlib Python formulas compute a deterministic maximum strength estimate without requiring a physically demanding maximum lift attempt.
