Training Hard to Fight Easy

Ultimate Gym NYC is the oldest and first authentic Muay Thai Gym in NYC and has been in business in Midtown Manhattan for over two decades.

Ultimate Gym NYC’s instructor, Kru Nestor Marte is considered a leading expert in the art of stand up fighting. When MMA fighters such as Renzo Gracie, Ricardo Almeida, Ryan Gracie, Anderson Silva, Assuerio Silva and Israel Gomes needed to train their stand up, they sought out Kru Nestor Marte to brush up on their technique.

Our facility is a comfortable 2500 sq. ft., fully equipped gym with Thai Heavy Bags, matted floors, boxing ring and all necessary equipment. We are the only gym in New York dedicated to teaching the exact training regimen used by all Muay Thai camps and champions in Thailand. We strive to provide a safe and fun environment for both our men and women, young and old, competitive and non-competitive students. Condescending attitudes and verbal attacks are not condoned and all our classes are co-ed.
