I have experienced tremendous improvement in strength, flexibility, and overall well-being since working with Patrick at Clientel3. And they take COVID safety protocols seriously and have managed through the pandemic with a commitment to clients' concerns, health risks, and need for flexibility.

You will find the highest quality of training and a level of expertise that you don't find at any other personal training studios. The facility is top-notch and they offer a variety of areas of focus. From lifting to MovNat, you can focus on your training interesting and seek new challenges

Started working out with Chi (and other trainers) about 3 months ago and i cannot recommend them enough. Chi has not only helped me reach my goals, but has taught me a new way of life - I am overall healthier & happier, all while eating more and working out less. These guys are the real deal. 5 stars!

The trainers here are super knowledgeable and very motivating. After years of working out on my own and with other trainers and seeing no results, I decided to check out c3. I wasn’t too hopeful given my previous experiences, but this place is different. I’m finally seeing results and feeling stronger.

Clientel3 is the MOST unique, clean, and professional fitness experience you can find in the city. Chi runs a TIGHT ship, and all of their trainers are of the highest quality. You don't go to clientel3 to "work out", you go to change your lifestyle permanently!

I have only good things to say about my experience at Clientel3. It's been an investment, for sure, but hands down one of the best I have ever made. The training is highly personalized, following a thorough fitness evaluation and a discussion of goals. Whatever your level of fitness (I was a cardio queen who could barely do three pushups when I started), you will feel welcomed and supported. And you will experience real (visible + measurable) results that will inspire you to keep up the good work. I honestly only planned to train here for three months, but now I can't imagine leaving

I really enjoy how much the exercises that I do at CLIENTEL3 challenge me to push myself. I have been training with Chi for awhile and I really enjoy the amount of thought and planning that goes into my workouts.

The space is amazing. The people sound and knowledgeable. The price is steep but worth it. You're in good hands.

I just participated in a six week challenge with Chi Bang bodies and the results have been phenomenal! Prior to joining this community I had plateaued with my own fitness efforts and could not understand why I had stopped seeing results. Through the past six weeks I’ve been taught how to properly portion my food, improved my form during workouts, and have definitely put on quite a bit of muscle. I truly thank for helping me meet my physical goal and getting this body all the way snatched!

The trainers at Chi Bang Bodies KNOW WHAT’S UP! The classes have you moving the whole time, and they definitely keep it fun and interesting! They work hard to cultivate a positive environment where anyone can get a great workout. If you’re a beginner, they teach you new exercises and help monitor your form. If you already have experience with weight training and interval workouts, they push you to lift heavier, move faster, and still try out new things! Overall most of the classes are awesome and a great way to shake up your fitness routine!

I came across the opportunity to be a part of this 6 week challenge in December. I was skeptical at first, but the chi bangs body staff quickly made me feel the confident about my decision of joining this training facility. All trainers are friendly, professionals and treat everyone with respect and patience. The work outs are challenging but certainly doable. Within six weeks, I was able to gain 10 pounds of lean muscle! They provided me with a diet specifying the portions and oz of the fats, carbohydrates, protein and veggies that I needed to consume to be able to gain muscle.
I totally recommend

I am finishing the 6 week challenge today as one of the successes, 20 lbs in 6 weeks with both fat loss and muscle gain. I've learned a lot of great tool to take with me from enhancing my nutrition plan to how to more effectively use resistance bands in training. A big thank you to the training team who have such great energy and passion for what they do. They are highly educated and focused on making goals attainable by working within your body's limits and keeping the energy up, even with down music.

Chi Bang Experience has improved my views on personal trainers and organized fitness. The dedication, enthusiasm, knowledge, sincerity, and love each individual has for their job is truly amazing. I am one to always find holes in some type of service one way or another and this I do not. They are everything they say! They push you with smiles and compassion. They make you want to not only drive yourself, but others around you. What an organization!

I was a 6 week challenger. I joined the program 5 months after I delivered my daughter and I was struggling with my image. I was very skeptical in my abilities to loose the amount of weight that was expected but I took the challenge seriously. Over the weeks I pushed my limits, enjoyed more and more the toughness of the workouts and the mastering of the exercises proposed. I learn to eat the right food amount and the most important point is that I feel better. I am glad I participated to this challenge, I have more energy and I know i am able to loose the weight I want to.

I recently participated in Clientel3's 6 week fitness challenge and I must say that the experience overall was a positive one. The entire staff is down to earth and passionate about fitness, which made each visit one I looked forward to. The dual class and nutrition model was built in a way that enabled me to see results in as little as a week and after 6 weeks I've seen changes in my body that I struggled to make over the past two years!

The facility, although small, is clean and full of cool and unique fitness equipment and is conveniently located at the Arlington T stop. The group

I really wanted to give them a good review. However participating in the 6 week challenge was a big mistake for me. Fastest way I have lost $600 in my life. They hand you a generic meal plan, which there is no way to prove that it will help you lose weight or body fat. They don't give you the copy of the contract and conveniently do not mention that you have to lose X% body fat to 'win' the challenge. Instead have stipulations like online check ins etc to max their publicity as a PR stunt.

The only good thing here are the instructors who are very knowledgeable , very hardworking

Awesome group of people! The trainers are great and will take the time to explain things and answer any questions you may have about workouts, recovery, etc. The other participants are highly motivated and supportive. Truly a great environment to be in and a great community to be a part of!

I did some of the workouts for the 6 week challenge and it was great getting a sense of community and inspiration during the workouts. I love incorporating my own modifications to make it harder for myself which the trainers themselves loved and I love MOST of the trainers there (I really despised one trainer there). My only issue was… miscommunicationS and one personal trainer but other than that, you're getting top notch training from MOST of the trainers, nutritional experts and family to help support you towards your personal goal. It was a little disorganized but I think of it as the

Absolutely incredible!!!! Those are the two words that come to mind when I think of Clientel3. Chi and his entire staff have absolutely changed my life. They offer a comprehensive training program from body to mind to soul. I have had a knee injury for 6 years and nothing has improved my condition... Within two weeks of working with Chi, I was doing pistol squats and running up stairs (something I haven't done in over 7 years). Their knowledge of the human body and more importantly, their commitment to their clients is evident in every single session you have at C3. I am just so thankful I
