Lives We’ve Touched

Real people achieving their goals

“Been going to OPEX for the last two years, working with coach June, and it has been immensely rewarding. I’m feeling the healthiest I’ve ever been and appreciate how close we’ve become with all the coaches at OPEX. Can’t recommend it enough.”

Skip B., Writer & Producer
Member since February 2020

“Chantel keeps my program dynamic, based on what’s going on in my life (like traveling, dieting, overdoing it in other sports or nights out) and has helped me get stronger, more resilient, and positively impact other areas of my life, like work and other fitness activities.”

Marlo T., Corporate Sustainability
Member since February 2021

“I highly recommend OPEX South Brooklyn to anyone who’s looking to develop good habits – whether that’s someone who wants to jump start their health and fitness, or someone who is a seasoned athlete looking to attack a new skill, sport or just a new life goal.”

Akshay G., Software Engineer
Member since January 2021

“Zack is my coach and I LITERALLY love him so much. I am not joking when I tell you, “It’s worth it.” OPEX SB has all the tools to help you succeed and if you’re serious about making a positive change in your life you would at least try it out. At this point, there is no one to blame but yourself.”

Joseph G., Project Manager
Member since January 2021

“This gym has truly been life changing for me. My coach Chantel has truly taken a holistic approach to my health and helped me create a plan that helps improve my fitness, my mental health, my sleep, my stress levels, my mindsets and my nutrition.”
