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 😀

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

I’ve been doing physical therapy with Ogbonnaya for over six months now and have nothing but great things to say. I’m prone to pulling my back a few times a year, and Ogbonnaya has been working with me to strengthen my body to prevent future issues. He explains what each exercise is doing and provides video instructions so that I can keep doing them at home. I now feel so much more confident in my form. I can be lazy when it comes to picking which weights to use and Ogbonnaya pushes me to use weights that he knows my body can handle. I’d highly recommend working with him!

I have been working with Clientel3 for several years and the results have far exceeded my expectations. I am in my mid 60s and very focused on keeping myself in shape so I can enjoy this chapter of my life. The team at Clientel3 has developed a program that works on my weaknesses and maintains my strengths. I highly recommend them to anyone looking to improve their quality of life.

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!
