I saw Ogbonnaya! So happy that I did. My calves were feeling tight even though I workout & stretch. He check them out, asked the right questions, assessed & began the work. I did exercises, corrective movements & received dry needling which helped. Thorough & worth the investment! I highly recommend 😀
My experience at CLIENTEL3 has been fantastic. I've been coming here for over a year now as someone who had experience with exercise and fitness as a college track athlete but wasn't able to keep up the discipline as an adult, especially after suffering 2 knee injuries. I was apprehensive and nervous at first to get back into things after 15+ years off but the trainers at CLIENTEL3 have been amazing - I've been working with Aidan and Grayson who have really been superb at helping me maintain my fitness goals. Furthermore, what has made CLIENTEL3 truly perfect has been the the physical therapy provided by Ogbonnaya. After having been inactive for so long, I realized that my old knee injuries were quickly becoming a road block to my progress. Ogbo has taken me from thinking that I'll be doomed to a lifetime of knee pain to being able to do more than I even thought possible. He's very skilled and goes above and beyond to adapt to my needs from session to session. Highly, highly recommend CLIENTEL3!!
I’ve been coming to this gym for about a year now, and it has completely transformed how I feel about fitness. Grayson has been my main personal trainer, and he’s genuinely exceptional — consistently prepared, incredibly knowledgeable, and always able to strike that perfect balance between pushing me and supporting me. He pays attention to the details, adjusts sessions based on how I’m feeling that day, and explains the “why” behind every movement. Training with him has made me stronger, more confident, and way more consistent with my routine than I ever thought I’d be. I’ve also had a few sessions with Chi and Aidan, and each of them brings something unique to the table. Chi, who’s also the owner, deserves a special mention. He’s incredibly kind, patient, and genuinely cares about every person who walks in. You can feel that the community and atmosphere here come directly from his leadership and personality. The gym is clean, welcoming, and never overcrowded. Workouts are tailored, effective, and actually enjoyable. After a year here, I genuinely look forward to training and feel better than ever. Couldn’t recommend this place more — if you’re looking for real personal training with trainers who truly care, this is the spot
Chi Bang of Clientel3 has been AMAZING to work with!!! As an older woman who had never used a personal trainer before, I wasn’t sure what to expect. However, the results speak for themselves! Chi designed the perfect program for me to become stronger and more confident with everyday movements. My goal is to remain active as I age, and Chi is giving me the tools to do so!
I can't recommend C3 Gym enough! From the moment I walked in, I was impressed by the state-of-the-art training facility. It's spacious, clean, and equipped with everything you need for an effective workout. What truly sets C3 apart is the personalized touch from the workouts all the way to the music in the gym. Additionally the trainers are incredibly dedicated, offering personalized attention and being available whenever I need them. Their guidance and encouragement have really helped me stay on track and push my limits. Thanks to the focus on functional training, my body feels better than ever! I've noticed increased strength and improved mobility, which have made a huge difference in my everyday life. If you're looking for a gym that truly invests in your success, C3 is the perfect place to reach your goals!
