EXCELLENT GYM! One thing that makes Union Performance stand out is that there are workouts programmed and ready for you. You can choose to do your own workout or do the functional strength training that the owner has planned for that day! I’ve been in the fitness space for quite some time and am VERY impressed with the quality of the workouts. These workouts are safe, effective, and very applicable to real life. There is even mobility work planned every day!! On top of that the community is incredibly kind and friendly! Union Performance is a special place!

The best gym environment I have ever been to! The programming is exceptional for all users. I love the vibe of the facility - I was previously a member at LifeTime and a CrossFit regular, but UP has everything I need in a great layout. The one thing that stands above everything else is the culture the members and trainers have created!

Best gyms I've ever joined. Robbie is a great coach and very knowledgeable. He really makes you feel welcomed and holds you accountable. He made me realize the difference between TRYING AND TRAINING! I would recommend this to anyone that wants to challenge themselves. Anyone that is tired of the norm. Anyone that wants to manifest the best version of themselves. I'm thankful for this gym and the community that trains here. ONE LOVE TO THE UNION PERFORMANCE FAMILY!

This is the best gym! The workouts are incredible and are different every single day so I'm never bored. I love the functional training aspect and feel myself getting stronger but not bulking up. Great owner, teachers and community <3

Best gym. Best people. Best atmosphere. Wouldn’t dream of going anywhere else. You won’t find trainers as knowledgeable anywhere else. Trust me.

I have always struggled to keep consistency with exercise. UP creates a community of people and a welcoming environment where you want to go back and get excited to go to the gym. We focus on long term goals and not getting a “quick fix” on health and wellness. Robby has made something really special here!

I’ve been training here for about a year and have nothing but postives to say about Union Performance’s approach. Robbie and the whole team is very knowledgeable and ready to help everyone become more functionally fit. I have noticed improvements in my strength, flexibility and core stability that keep me coming back for more. Be a part of the UP community!

Truly the best gym. The workouts are very well thought out. Members are genuine. Robby will elevate your fitness and change your mindset - if you’ll listen. I’ve been going to UP for 3 years. This program has produced significantly more results than anything else I’ve been a part of. It’s not 45 min of gasping-for-air, extreme intensity. It will challenge you. The program is effective. Highly recommend. No mirrors, no meatheads. 🤗

I have been within the health and fitness industry for 20 years, and the trainers at UP do it at a level that few can match. Their knowledge of how the body works combined with their continued effort to learn new things makes UP a perfect place for anyone who is looking to increase their level of health.
