Notes for first-time students

Muay Thai is widely accessible from age 7 through your 50s. Kids under 7 are usually better suited for karate or taekwondo, which have more structured curricula. Adults over 50 can absolutely start — just choose a gym that emphasizes technique and pad work over hard sparring, and progress your shin conditioning slowly. Anyone with knee or hip issues should talk to the coach about modifying kicks before the first class.
