Mauy Thai.


This physical and mental discipline which includes combat on shins is known as "the art of eight limbs" because it is characterized by the combined use of fists, elbows, knees, shins, being associated with a good physical preparation that makes a full-contact fighter very efficient. Taught by our very own, Donnie Hunt - a seasoned fighter under Phil Maldonado, Jon Marsell and Kaensak (Pongsak cheawchan). If you are looking to just get in shape or learn how to fight, our Mauy Thai classes are designed for you.
