I was looking to make a positive, sustainable change, and Sean's comprehensive, highly personalized approach to fitness is perfect.The environment that Sean has cultivated is welcoming and supportive while also geared to push you forward. Coach Andrew and Adam are experienced, encouraging, and constructive. Gym members are of diverse backgrounds and fitness levels.I've had such a positive experience at OPEX that I have a hard time thinking about ever leaving Baltimore because this is as good as it gets in terms of health focused, no BS, customized, safe fitness.

This is hands down the best gym experience I have ever had. Sean makes personalizes workouts that load into your app each week, so you know your workouts coming up. When you get to the gym, either Sean or one of the other great coaches will make sure you know what you are doing and are there to assist in anyway.Some nice things about the set up: never a massive amount of people since all clients of Sean and team; monthly appointments with Sean to go over progress and any roadblocks, over just nice people here.Highly recommend

THIS IS THE BEST KEPT GYM SECRET IN BALTIMORE! I joined this gym about 3 months ago after spending the past 4 years at various other gyms throughout the City. As soon as you walk through the door, you know this is the place for you. What's great about this gym is not only the atmosphere, the personalized exercise and weight training programs developed by the coaches, but also the different skill levels and types of people. There's no judgement here. A coach is always on the floor to assist you with form and technique. What's also great about the gym is Coach Sean. He's a former D1 coach who knows how to motivate individuals to get you to give your maximum effort. OPEX Baltimore has changed my life and outlook about fitness. I highly recommend you check this gym out. You will not be disappointed!

After not being able to exercise for over 3 years, OPEX Baltimore and Coach Sean welcomed me exactly where I was with no pressure to be anything but what I was. It’s great to be met at my level while others being given the same. Plus I love that there are so many different types of people and bodies there. Anyone and everyone is welcome!

I joined OPEX Baltimore South about a year ago and OPEX coaches (Sean, Andrew and Adam) are very knowledgeable and personable coaches. This program is personalized to you as the individual which is great! I know I can't do alot of the exercises like I use to when I was younger. They have alternative exercises if certain parts of your body hurts. Sean is very passionate about what he does and always listens to your concerns and provides suggestions to help his clients and does not judge. He also uses TrueCoach which a great app/site to keep track of your exercises and it's a great way to communicate with you directly.

OPEX Baltimore, specifically Coach Sean McCullagh changed my whole perspective on fitness, nutrition and over all life balance. I've been involved in a number of "fitness" programs, but nothing compares to OPEX’s wholistic individual approach. Not only am I stronger and more physically fit, I have way less over all stress, sleep better and feel faster, stronger, smarter in all other parts of my life. Finding OPEX Baltimore was the best choice I ever made and there is no looking back. I look forward to all the great things ahead!! Huge thanks to Sean and all the dedicated coaches at OPEX Baltimore!!

I’m a full time working mom of 2; meeting the needs of my family and finding time for personal care and fitness can be challenging. In the past 4 years of seeing my two kids grow I've certainly sacrificed weeks of not working out or taking this time for myself. At OPEX Baltimore my fitness program is tailored to my needs. I can get my training in, feel good about myself, and still feel confident about my roles of running a household of two small kids. My bodyweight has gone up and down as I grew two babies and shared my body with them. I’ve received excellent advice on nutrition for breastfeeding moms, nutrition during pregnancies, and now am receiving advice on nutrition so I have the energy for two small kids. The coaches are amazing, the community so welcoming, with one common goal of bettering lives.
