Great private gym. Everyone is very interactive and friendly. When you enter Flex, you just want to put that work in and work out. The gym atmosphere is totally different from my other gyms. The staffs and trainers are very respectful as well. I would recommend this to anyone who is serious about their fitness journey or is seeking guidance in fitness!

I’ve been going to Flex Warehouse for 4 years now, and I can honestly say it’s one of the best gyms out there. I love seeing how much it’s grown over the years — the atmosphere, the community, and the constant improvements make it stand out. The equipment is top-notch and handpicked from all over California, which really shows in the quality and variety of machines. Flex Warehouse just keeps getting better, and I’m proud to be part of it! 💪

This gym is great. Not as big or as fancy like other gyms but definitely the best one to start. Super recommended for beginners like me who wants to start with their training journey. Everyone here is friendly and everyone is welcome as well. I was a client here and the trainer is very knowledgeable and definitely knows his stuff. Now I’m a member here and I’m glad I found this place. 👍👍

Flex Warehouse is always my go-to gym whenever I’m back in town visiting family and friends. Being in the military, I have access to gyms on post, but honestly, the equipment doesn’t even come close to what Flex Warehouse has. I know I’ll always get a solid workout in, even when I’m on vacation.

I love the chill, judgment-free vibe, and Kou is always super helpful, whether it’s one-on-one training or just showing you how to use the machines the right way so you don’t hurt yourself.

Kou, I’m pumped to see what the future holds for you and your family. 🗣️Let’s get it!💪💪💪

I was gifted 8 training sessions with Trainer/Owner Kou, and I can honestly say that it was the best gift I could ever ask for to kickstart my health journey. Kou is knowledgeable, encouraging and supportive in helping me reach my goals. The facility is clean and equipped with everything you need. I also appreciate the sense of community here; it's welcoming and non-judgmental zone makes working out something I look forward to. I enjoyed the sessions so much that I signed up for more. I highly recommend Flex Warehouse to anyone searching for a professional, motivating, and results-driven environment.

Flex Warehouse is exactly what I needed. Unlike the big-name gyms that feel crowded and impersonal, this place offers a refreshing, down-to-earth environment that actually makes you want to show up and work out. Kou clearly puts a lot of heart into the space. It’s clean, welcoming, and full of great energy. Whether you’re new to fitness or just tired of the same old routine, Flex Fitness gives you a real sense of community and motivation. Highly recommend if you’re looking for something different that actually works.

I have known the owner for 17 years, trained with him the first 5. I have trained all around Fresno and surrounding counties, the passion Kou has for the art of building ones self is second to none, having the privilege to train at the FLEX WAREHOUSE has been the best 2 years of my training experience. Thank you Kou, for creating an establishment with culture and grit and honest hard work.

Flex Warehouse in Clovis is hands down the best gym I’ve ever been to, and a big reason for that is Kou Chang! From the moment I walked in, Kou made me feel welcome and part of the Flex family. He’s incredibly knowledgeable, always willing to offer advice, and genuinely cares about helping everyone achieve their fitness goals.
The gym itself is fantastic – spacious, clean, and packed with high-quality equipment. No matter what your fitness level or style is, Flex Warehouse has everything you need, and Kou makes sure you feel comfortable and motivated every step of the way.
Kou’s energy is contagious – he’s the kind of person who makes you want to push yourself harder and enjoy your time at the gym. He’s not just a staff member, he’s the heart of Flex Warehouse!
If you’re looking for a gym where you’ll feel supported, inspired, and part of a real community, look no further than Flex Warehouse in Clovis. And if you get the chance to meet Kou, you’ll know exactly what I mean. Highly recommend!

This is a great gym with all the metal weights which makes lifting a whole other experience compared to the commercial plastic weights. One of the great things about this gym is you get to go in whenever you want without having to check in with anybody. It’s a quick work in and out due to not being jammed pack with people. Price for membership is also great for what you’re getting it for.

This gym stands out as one of the best I've experienced. It embodies a no-nonsense approach to fitness—just pure, focused training without unnecessary frills. Kou, the owner, creates a welcoming atmosphere and genuinely cares about maintaining quality equipment. The space never feels overcrowded, which allows for uninterrupted workouts, and the extensive variety of equipment accommodates different training styles. For anyone into old-school bodybuilding, this place captures that authentic, serious training vibe perfectly. It's a gym for people who prioritize substance over flashy amenities.​​​​​​​​​​​​​​​​

I’ve trained at several gyms in Fresno, but Flex Warehouse stands out. The equipment is handpicked to train each muscle group effectively, so everything you use serves a purpose. I work with Kou, the owner, and his coaching is on point. He takes the time to explain his methods and pushes you to improve. The members here are serious about their goals and supportive of each other. If you think you train hard, try one of Kou’s leg days and see for yourself!

Great private gym! Every time I come in, equipment is readily available, and I can get straight to my workout without any delays.

The people who go here are supportive and respectful, which makes a huge difference when you’re trying to stay motivated.

Big shoutout to my trainer Kou - he is patient, attentive, and really takes the time to understand your goals. He works with you every step of the way, adjusting workouts to fit your needs and pushing you just the right amount.

If you’re looking for a clean, low-key gym with a great community and top-notch personal training, this is the place. Highly recommend!

Flex Warehouse offers a unique atmosphere you won’t get anywhere else. It’s a small community of friendly, genuinely hardworking and likeminded individuals. Members are respectful of the space and one another. It’s truly been an honor to see the members grow physically and mentally. In addition to the exceptional culture of the gym, FW also offers unique equipment that has challenged me to achieve PRs I’d never imagined possible. The trainer and owner of the gym is passionate about transforming the mindsets and confidence of his clients and members. Being a part of Flex Warehouse has been a worthy and transformational investment!

I've been training with personal trainer-Kou for a few months, and it's been an incredible journey. His flexibility with schedules and training methods, allows me to keep up with my workouts despite a busy schedule. He focus on teaching the right way to do each exercise and he understands muscle mechanics very well and shows how to engage muscles properly, which has really helped improve my strength and muscle growth!
