Fitness and fighting made fun!

Our curriculum is structured and accessible to all interested students: some join without the desire to compete, while others are primed for the ring.

Kickboxing / Basic Muay Thai

Our beginning kickboxing/ Muay Thai classes are high energy and high intensity training that will leave you dripping in sweat! Students will learn the basic techniques (boxing, kicking, elbows, knees) while becoming lean and fit. Classes are held on weekday evenings and Saturday mornings.

Advanced Muay Thai

Chaisai’s advanced Muay Thai program is taught by former World Muay Thai champs and Hall of Fame inductees Kru Alberto and Kru Ariana Ramirez. Our advanced Muay Thai program kicks things up a notch from the basic foundation you learned with our beginning classes.
