Map any exercise to the exact muscles it works. Primary, secondary, and stabilizers — structured for AI agents, fitness apps, and health platforms.
Every fitness app needs muscle-mapping data — for exercise suggestions, workout analysis, muscle balance tracking, and personalized programming. But curating accurate anatomical data is a massive undertaking.
// Query any exercise GET /api/v1/exercises/bench-press/muscles { "exercise": "Barbell Bench Press", "primary": [ { "muscle": "Pectoralis Major", "group": "chest" }, { "muscle": "Anterior Deltoid", "group": "shoulders" }, { "muscle": "Triceps", "group": "triceps" } ], "secondary": [/* 6 muscles */], "stabilizers": [/* 5 muscles */] }

Know exactly which muscles any exercise targets. Your users ask “what does bench press work?” and you answer instantly.
Your users ask “what exercises work my chest?” Answer with filtered, relevant results in milliseconds.
Help users discover they’re neglecting hamstrings before it causes an imbalance. Flag gaps automatically.
User doesn’t have a barbell? Suggest the closest dumbbell alternative automatically, ranked by muscle overlap.
Handle typos gracefully. “bench pres” still finds Barbell Bench Press. Built for real user input.
Equipment, difficulty, force type, laterality, movement pattern. Every exercise fully classified so you don’t have to.
From AI coaching agents to rehabilitation software — structured exercise data powers it all.
