TRAINER SERVICE AGREEMENT

Last updated August 8, 2026

IMPORTANT:This Trainer Service Agreement is in ADDITION to Muscle App's general Terms and Conditions. By offering services as a trainer on the Muscle App platform, you agree to BOTH documents. In case of conflict, the more restrictive provision applies.

This Trainer Service Agreement ("Agreement") is entered into between Muscle App("Platform," "we," "us"), a company registered in Spain at Alcalá de Henares, Madrid 28805, and you ("Trainer," "you"), the individual or entity offering personal training services through our platform.

By creating a trainer profile and offering services on Muscle App, you acknowledge that you have read, understood, and agree to be bound by this Agreement.
