The trainers here are incredible. They keep a group of 5-7 energized and make the workouts really fun, while tailoring to each person’s individual goals. Further, they teach you how to lift effectively and safely, which I appreciate immensely since I travel for work quite frequently.

Flexx is by far the best workout place I've ever joined. The workouts are challenging but fun, coaches are fantastic- they make sure you are doing the rounds correctly and push you when needed. The community of members makes Flexx a Family! Best decision I've made, 3 years running.

Where do I begin! If I could give 10 stars, I would. It started with Tyler one of the owners! He really listened to what I needed and passed that info along to his trainers. This small group personal training is the best. That is because of the small groups which allows for some one on one experience and specialized training in a small group setting. The members are all kind and have the same goal in mind. We all want to be better and stronger. I have been with FLEXX for 6 months and can’t imagine what it would be without them. They have helped me rebuild muscle and strength that slowly started disappearing. Love the whole team and the overall experience. You won’t be disappointed. The trainers Caj, Zach and Sabrina are truly awesome.

2024 review:
Joining Flexx has been the best decision I've made for myself in the last year. Quinn is focused on creating effective and time-efficient workouts that are supportive of my personal goals. Quinn also has nurtured a vibrant and supportive community of members, making it fun to leave a pound of sweat on the floor.

Tyler is the best fitness coach you will find anywhere. His enthusiasm is infectious and makes even the most grueling workouts fun. He cares passionately about your fitness and results will come quickly. I've been working out there for about 3 months and I'm the strongest that I've ever been and losing weight. I'm easily in the best shape of my life thanks to Tyler. I give this place my whole hearted recommendation for anyone who wants to improve their physical health.

The workout has a great format from warm-up and stretching, compound lifting movements, pump circuit, and a cardio boosting finisher each session. Safety and proper lifting techniques are always a priority. A positive, motivational and inspiring atmosphere is a focus of each class.

I joined Flexx a couple weeks ago and already love it! After not working out for a while, I needed the motivation and guidance that only small-group training can offer. It’s pricey but I would say it’s worth it. Best trainers I’ve had in a while, they make it challenging and fun! Coach Quinn is great!

I've been training at Flexx for a year now, and can very enthusiastically recommend the experience.

Classes are personalized to your abilities and strengths, no matter how diverse in skill the group is. I love that the groups are always kept small so that there is plenty of individual attention. The trainers are always positive and energetic, and foster an encouraging environment between clients. Each session's overall structure is consistent and predictable, but the individual exercises change often so you're never bored.

If you have no fitness knowledge and are looking for a motivating and safe space to train, I'd definitely check out Flexx!

So my wife and I have been going to Flexx Gym Arlington Heights for about 4 months now. During that time we've been training with Quinn and I have to say these have been the single best training sessions I have ever done. The energy from Quinn really gets you excited to work out and he challenges you while also taking into account limitations that can crop up. The workouts while challenging, are measured and well structured. Not insane or too easy. Overall this has been the best experience working out I've had yet and would highly recommend it!!

Flexx is one of my favorite places to be. From day 1, Tyler and Quinn made me feel welcomed, wanted, and encouraged. That's maybe a lot to ask from a gym, but it's really just the beginning. Not only have I gotten (so much) stronger in my year at Flexx, I've never felt anything but accepted, which is not super common in fitness spaces. I've never felt uncomfortable in my own skin or been made to feel ashamed of my body, by anyone -- it's the best, most encouraging community. They will say it's because only great people come to Flexx, and that's true, but that wouldn't happen if Tyler and Quinn didn't set the tone every day. I am very grateful. Best decision I've made in the last year.

Flexx is an amazing place to get a great workout in a friendly environment that's tailored towards your ability level and health goals, while also taking into account any injuries or problem areas you might have. Tyler and Quinn are both incredibly friendly and welcoming, and they both help motivate you through the workout while being flexible to change things up if any of the exercises aren't feeling right to you. The individual attention they provide while creating such a fun, high energy atmosphere that many gyms or other exercise facilities don't generally have is incredibly refreshing and appreciated. If you're looking to get back into working out, want to improve your health, or just want a change of pace in atmosphere for your exercise routine, Flexx is an amazing place to go! Looking forward to more split squats, Tyler and Quinn!

You couldn't ask for a better personal training facility than Flexx. Tyler is very personable. He stays in touch with your needs and adjusts all your training to your aliments. He makes sure the exercises you are doing won't hurt you and checks in through the routine; if it hurts you he changes it up to something you can still benefit from but won't hurt. You won't find a better personal trainer than Tyler.
