We have gyms and then we have OPEX !!! John and his wife and staff are all legit, extremely knowledgeable about any and everything. This gym goes above and beyond to get to know you and help you achieve your goals. THE COACHES ARE PURPOSE DRIVEN , and I write that in cap because they do have that passion that people need to change those bad habits and develop good ones. Very pleased so far but the best is yet to come, Evey day I hit the gym I know I am taking one more step to that OPEX in my life. Blessed to find this place for sure. THANKS OPEX Mount Sinai!!!

Great personalized training tailored to meet your individual goals. I’ve been coming to OPEX Mount Sinai for 7 months and this is the best I’ve felt in years! The coaches are wonderful, extremely caring and knowledgeable, they always make sure I stay on track even when I’m traveling.


I have been coming to Opex for over 6 months and I can’t say enough positive. The fact that the training is personalized for my wants and needs is what makes all the difference. The guidance and training given fit my lifestyle and goals. I would recommend anyone to come here if you really want to see a change.

Jennifer J. Maertz,

If you are looking for semi-personal training and a supportive environment, Mt Sinai Opex is for you. You get a personalized workout plan to achieve your goals whether its losing weight, getting stronger, sculpting muscle or recovering from injuries or all of those things. In addition to the face to face monthly evaluations you also get a monthly computer read out of your improvement including weight changes, body fat, water, and muscle mass in different areas of your body.

It’s not the type of gym where you work out with 50 different random people each day. (You generally only work out with a handful of people each day, each on your own program and your own schedule.) You get to know and support one another in a non-judgmental manner while also focusing on your individualized training. Each workout is delivered to you on an easy to use app and trained staff/owners are there to guide you as needed and help correct your form including suggestions for overcoming or avoiding injuries.
