About Us

Intensity Fighting Arts started as the private training facility of Husband and Wife team James and Kathy Criveau. "We decided to set up our own gym where we could train ourselves, friends, and other fighters. With the success of these goals, we decided to open up to the public, so we could pass this on to those around us."

What people are saying about Intensity

"Thank you very much for Monday's class. It was spectacular, looking forward to more."

I have been a member of this school since early March and at 40 years old and never having taken up any form of martial art, I wasn't sure what to expect. I am really happy that I walked in with an open mind, many weeks later I can truly say I am very lucky to have found trainers like the ones at Intensity."

Intensity Fighting Arts is THE place to learn Muay Thai Kickboxing in New York! I have been training there for a few months and I have experienced great results-in my balance, confidence, boxing skills and overall improved fitness. Auto and Kathy are great trainers that are intense, dedicated and push me to my limits and beyond. Their teaching style focuses on and reinforces the basics as they add their personal life and fight experience to the very up close and personal training they give each and every session. The class sizes are small , by design, to make sure students get the proper training to become excellent muay thai kickboxers. They take the time to explain how the moves and drills help to develop you into a better fighter as they know from their own experiences. I travel over 30 minutes every Monday , Wednesday and Friday and sometimes on Sundays to train at this gym. Well worth the trip as this training and experience is priceless and very personalized. This is the best thing I did to get myself in great shape while at the same time developing fighting skills that are second to none.
