I was an ECF member for several years when they were located in Lynbrook and I have to say that the instruction and training you will get here is far superior to other gyms that advertise similar programs. Owner Sensei/Coach Christian is a phenomenal athlete and former pro MMA fighter and his workouts and fight training will get you into the best shape. Although the classes are no walk in the park and you will work hard and sweat, ECF caters to all genders, body types, and ages, whether you are just looking for fun and fitness, or you're hoping to fight professionally, you will be training

I started at ECF in Lynbrook back in January and it was the best decision ever! I started with taking boxing and Kickboxing and recently started Brazilian jujitsu. The classes are great because they cater to all levels, beginners and advanced. I am not very coordinated and its hard for me to remember the moves but that doesnt matter at ECF. The Coaches are so patient and always check on each student in the class to see if we need help and make sure we get the technique down. I never thought I would be a gym person but ECF makes it a learning experience while getting a serious work out and

I've been a member of ECF for a little over a year, and through these trying times I couldn't be happier and more proud to be a member. The facility is top notch and the staff goes above and beyond to make sure that the facility is clean and there is proper training equipment for everyone. The classes available can satisfy every age group and experience level, and the personal training that professor Christian provides is unmatched. Whatever you are looking to do, whether to get in shape, compete, or learn a martial art, this is the place to go.

As a current member of the military & former wrestler, I have been to many gyms on Long Island and although I do appreciate what Ive learn from those gyms, none compare to ECF. I have been training here for a few months now and they have provided well organized/quality classes for their members. The owner Christian and his staff are great mentors and heavily involved in the progression of their students. I hope this helps anyone who is looking for a good gym to call their home.

I just started coming to this gym. It's different than most other gyms. It's full of state of the art equipment and extremely clean. The instructors are super motivating and caring. They teach an awesome cardio-kick boxing class at 7:00pm that I really enjoy. You have to do a temperature check at the front door, and fill out a covid questionnaire each time you come to the gym.
