#fitness

A complete exercise and workout database covering 870+ exercises: search and filter by target muscle, required equipment, category, difficulty level, force type and mechanic, fetch a single exercise with step-by-step instructions, primary and secondary muscles and demonstration images, pull a random exercise matching any filter, and read all available facet values to build filter UIs. Every endpoint accepts input via the query string or the request body and returns lean, predictable JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for fitness and gym apps, workout planners, personal-trainer tools and health platforms.

A complete health & fitness calculator suite in one API: Body Mass Index with category and healthy-weight range, Basal Metabolic Rate (Mifflin-St Jeor and Harris-Benedict), Total Daily Energy Expenditure with weight-loss/gain calorie targets, macronutrient splits (balanced, low-carb, high-protein, keto, endurance) with fibre, U.S. Navy body-fat percentage, ideal body weight across four classic formulas (Devine, Robinson, Miller, Hamwi), and daily water intake. Every endpoint accepts GET query parameters or a JSON POST body and works in both metric and imperial units. All computation is done locally with established public-domain equations, so responses are instant and the service is always available. Ideal for fitness trackers, nutrition apps, telehealth and wellness dashboards.
