I’ve been a member for just over a year now, and my trainer Gene has completely transformed my fitness journey with his personalized attention and genuine investment in my progress. What sets this place apart is the refreshingly non-judgmental atmosphere—everyone from beginners to advanced athletes feels welcomed and supported without any intimidation or comparison. The staff greets you by name and remembers details about your goals, creating a community feel that makes you actually look forward to showing up. Whether you’re just starting out or getting back into fitness after a break, this gym provides the perfect blend of professional expertise and warm encouragement.​​​​​​​​​​​​​​​​

I can’t say enough good things about Sigma and especially Andy! From day one, she made me feel welcome and supported. She really knows how to push you while keeping things fun and positive. You can tell she genuinely cares about her clients and pays attention to every detail, from form to mindset.

Thanks to Andy, I’ve become not just stronger but also more confident in my training. The energy at Sigma is awesome, and the community here makes every session something to look forward to. Highly recommend checking it out, especially if you get the chance to train with Andy!

I just took a Pilates class at Sigma Performance Training and loved it! The small setting makes it very personalized, and Victor was a great instructor—he focused on the muscle groups I wanted to target and gave helpful corrections. Of all the Pilates classes I've taken before, this was the first one where I felt truly challenged. Definitely recommend if you’re looking for a workout that pushes you while still focusing on form and technique.

Having been a member at both Lifetime and Equinox, I can confidently say this gym is on another level. They truly care about you as a person you’re never just a number here. The space feels intimate, never overcrowded, and it’s always spotless.
They offer excellent Hyrox classes led by Jonathan, who is incredibly knowledgeable and will get you fully prepared. There’s also Pilates with Mirna (available on ClassPass), and she’s always booked clearly, she’s in high demand for a reason!
I’ve been training with Taylor since the summer, and I couldn’t be more grateful. She’s been amazing, not just with my workouts but also with my nutrition, making sure I feel supported every step of the way.
Carlos has done an incredible job building this team, and I can’t wait for the sauna to open it’ll be the perfect finishing touch!

I found Sigma Gym when I was looking for a place for my 14 year old son to learn the basics of weight lifting. It was the perfect, supportive environment for him....oh wait, and me!! You just can't help but want to be part of the positive energy that exudes from the place. It feels like the Cheers of the gym world, "everybody knows your name and they're always glad you came". My son works out with Jonathan, who has become a mentor and friend. I work out with Carlos and Emily, who each push me in different complementary ways focused on form and technique. I highly recommend joining the group classes, where the camaraderie builds muscle and forms friendships.

I’ve been attending small group training sessions at Sigma for a year now, and it’s been an incredibly rewarding experience. My trainer, Emily Garza, continues to challenge me in ways I never thought possible, all while maintaining a positive, encouraging spirit.
Over time, I met so many wonderful people at Sigma, and I’m consistently impressed by how knowledgeable and approachable all the trainers are. Recently, I’ve also begun incorporating Pilates classes into my routine, and I truly enjoy the balance it brings when combined with weight training.

I joined Sigma four months ago after a friend’s recommendation. It became a treasured experience and I’m finding myself spending more and more time there.

Before joining, I’d trained with a remote coach, not a gym, and my results plateaued. With Sigma, I see constant improvements in my strength, cardio fitness, energy, and mood. I strength train with Sawyer twice a week, do a solo cardio session once a week, and drop in occasionally for a Pilates class with Irene. Sawyer is truly excellent - experienced, versatile, funny and deeply dedicated to his clients’ success. Irene is also a fantastic passionate, positive and thoughtful instructor.

I’m continually impressed with the personalization and quality of services and engagement their team provides. Trainers are highly experienced, flexible and friendly. I’m paranoid about injuries, and it feels great to be supported and guided gradually, while also pushed to satisfying results.

The gym is young and small, so it can get a little crowded, but because of how versatile the equipment is and how conscientious the trainers and clients are, I feel welcome and able to get to work even when it’s busy, without feeling disturbed or disturbing others. Whether I want to be social or keep to myself, I always feel comfortable.

It’s certainly pricy, but you get what you pay for, and my life has improved dramatically, so it’s worth it for me. I recommend it to anyone.

Carlos and Mirna run a great gym. All the trainers cater workouts to your goals and needs, work around injuries or problem areas, and are friendly and fun! I wouldn't work out anywhere else.

UPDATE: My first single rep max at Sigma (about 15 months ago) was 335 lbs. This morning, I pulled 335 lbs for 3 sets of 10. I would not have seen this kind of progress anywhere else. Carlos, Mirna and the staff are the best. Hands down.

Sigma Performance is hands down the best gym I’ve ever been to! The facility is spotless, well-equipped, and has such a welcoming atmosphere. But the real star here is Keith. He’s the absolute best trainer. He genuinely cares about your progress, takes the time to understand your goals, and pushes you to be your best without ever making you feel intimidated. His workouts are challenging but fun, and his knowledge of fitness and proper form is unmatched. Whether you’re a beginner or experienced, Keith knows exactly how to tailor your training so you see results.

I’ve been working with Carlos for about 10 months now and I am in the best shape of my life. I’m stronger than I ever thought I could be, and I look and feel great. Can’t say enough about him and the awesome team he has at Sigma.. a great group of trainers who really know their stuff!

Wonderful trainers that are knowledgeable and truly want to see you achieve your goals. Keith and Emily have challenged and encouraged me to stay consistent which I imagine has not been easy. I started weight training in my 40’s which is a tough place to start but having an entire gym rooting for your success is priceless. Thank you to Keith, Emily, Carlos, Mirna and the entire Sigma crew who have become like a second family.

If you’re looking for a personal trainer, I highly recommend Keith!! I couldn’t be happier with the results. He kept me motivated, pushed me, and helped me reach my goal. Within a few months I was down 12lbs and lost inches off my waist. Every session was challenging and tailored to me. He also always had a positive attitude, which is a plus for 5am sessions. I highly recommend Sigma and highly recommend Keith!

Sigma offers knowledgeable trainers with a focus on health, wellness, mobility, and athletic progression. The trainers have established an environment that is safe and supportive while maintaining rigor. Each trainer offers specific knowledge and strengths and are effectively assigned in accordance with clients needs.

The most significant detail is the amount of support offered. Support that goes beyond employment obligations, such as when they showed up to run with and cheer for my first 5k! Sigma shows up and shows out!!

I’ve been a client at Sigma for over a year now. First let me say the energy is always amazing. You could walk in sluggish or maybe just having a bad day and I guarantee you that will change once you leave. The environment is more than just a gym it literally is a family. From the trainers to the clients. There is never a dull moment. They also give back to the children in the Houston community. Backpack and school supplies to toys for kids in underserved communities. With these coaches you will receive results because they lead by example. Carlos and Mirna the owners have done a phenomenal job. So if you are looking to not only look better but feel better look no other than Sigma Training. You won’t regret it!!!

I’m so happy I worked up the nerve to schedule a trial session at Sigma and invest in my health. As someone who is “gym shy”, I immediately felt comfortable after meeting Carlos and Mirna. They have created a space where everyone can feel comfortable and supported no matter your fitness level. The trainers at Sigma are all engaging, motivating and extremely knowledgeable and seeing other clients grow and achieve their goals is also inspiring. I have trained with Andy since day one and more recently started training with Sawyer. Both are communicative, always push me towards success and guide me on leading a healthy lifestyle outside of my sessions. I have learned so much from them both. Even on days when I’m burnt out or lacking energy, I never regret walking through that door and putting in the work. Joining Sigma was both the physical and mental wellness boost that I didn’t know I needed. Excellent experience!

I’ve been to many gyms, but Sigma is different.
I still remember how nervous I was walking in on my first day. One year later, Sigma has completely changed the way I feel about fitness and about myself. It’s where I discovered powerlifting, something I never expected to love, and it’s now a huge part of my life. What makes this place so special is the people. All the trainers are amazing . They truly take the time to understand your goals, your hesitations, and what you need. They see your potential and strength, even when you can’t yet see it in yourself. Carlos and Mirna, the owners, are the heart of it all. You can feel their passion, professionalism, and experience in every detail of the space. They care deeply not just about training, but about every person who walks through the door. Whether you’re looking to compete in powerlifting, Hyrox, running, Pilates, or just want to feel better in your body, you’ll find your place here. Sigma isn’t just a gym. It’s a space where you are truly seen, supported, and empowered.

If you’re looking for a big box people watching experience, a night club or a country club then this is the wrong place for you. If however you’re looking for a concierge level of detail and care for your personal fitness and health goals that meets you exactly where you are - from beginner to elite athlete - then it’s not only a great option, is it THE place. The structure of requiring personal training for membership adds a level of commitment that makes a huge difference. Mirna, Carlos and team are the best in town and it’s not close. If you’re committed to it and want to change your life, go here.

I have worked with Mirna Espari for more years than I like to admit. I had trained with others before Mirna, but had largely plateaued. I was in my late 40s when I met Mirna. I was dealing with a lot of physical limitations at that point. Mirna’s patience and professionalism changed my life. I got healthier, stronger, and fitter. I had never attempted power lifting before and Mirna convinced me to try. I am still lifting, but have added Pilates to my routine. I will never be someone with a lot of flexibility, but Pilates with Mirna has made a huge difference. I am in my mid (maybe late) 50s now and am in better shape than ever.

I have to share my amazing experience at sigma! As a 40+ female who has noticed my muscle tone to decrease with age, I've become determined to incorporate strength training into my workout routine. I couldn't have found a better place to do that!.

My trainer, the one and only Emily, is incredible! She's got the sass, smarts, and strength to push us through some intense workouts even when we want to quit. Since I started training with her, I've noticed a dramatic increase in my energy levels and a significant appearance in my muscle tone. I’m also much more confident using weights now. At the group trainings everyone motivates each other and it's been great to meet so many other Moms that understand the importance of staying healthy and strong.

I have been training with Carlos for 5 years and can say he has improved my strength drastically. When I first walked into the gym, I was too weak to deadlift the bar and we had to use kettlebells. Now I deadlift 385 pounds and qualified for powerlifting Nationals. If you are looking for a personal trainer to help you reach your fitness goals, I can't recommend Carlos enough.

I’ve been training with Carlos since 2019, and his expertise in strength training is impressive. When he opened Sigma Gym, continuing with him was an easy decision. Carlos has a deep understanding of body mechanics and tailors workouts to overcome limitations and maximize results.

The Pilates sessions at Sigma are equally amazing. Mirna and Victor are highly skilled, and have significantly enhanced my flexibility and core strength. Highly recommended for those looking for tailored, effective training.

Sigma Performance has been the gym where I have consistently worked out and have thoroughly enjoyed the process of becoming healthier and stronger under the guidance of their personal trainers. Victor, one of the trainers, has been exceptional in his ability to motivate and encourage with proper caution. Victor is widely regarded as an exceptional trainer, and for good reason. Not only is he extremely knowledgeable and experienced when it comes to physical fitness, but he is also friendly and approachable, making him an ideal trainer for individuals of all levels of fitness experience. As a first-timer, I found this gym environment to be non-intimidating, largely due to the welcoming nature of the owners Carlos and Mirna, who consistently exude a positive and upbeat attitude. Overall, I am grateful to Sigma Performance Training for the confidence it has given me in prioritizing my health and self-care journey.

After 8 years in the Marines and power lifting lately I thought I had everything I needed as far as power and strength. I was way wrong!

I joined Sigma the day they opened to do Pilates with Mirna and have 0 regrets. I lift weights regularly and played football for a good chunk of my life which caused a 5mm herniated disk. My back would go out just from picking up something off the floor sometimes but since I have been working with Mirna I have never felt better. It has helped not only my back but my workouts are better and doing every day things feel much easier. The environment that Mirna and Carlos have created is great for anyone from beginners in working out to experts. They are personable, motivating, and make you feel like you are right at home with family.
