About CKO Clark

Founded in 2018 by Charles and two former partners, our gym began as a dedicated kickboxing space fueled by passion, grit, and community. Over the years, we’ve helped hundreds of people discover the power of movement through high-energy kickboxing classes and real-world fitness training.

In April 2024, Charles took the reins as the sole owner and head coach, bringing a renewed vision and focus to the gym. With the rebrand, we’ve evolved into more than just a kickboxing gym—we’re now a functional fitness space offering small group strength training, personal coaching, and kickboxing that’s built for everyday athletes of all levels.

At our core, we believe fitness should build strength, confidence, and resilience both in and out of the gym. Whether you’re looking to hit harder, move better, or just feel stronger in your day-to-day life, our training programs are designed to help you level up—with expert coaching, personalized support, and a tight-knit community that’s always in your corner.

Welcome to the new era. Same fight. Stronger foundation.

The CKO Clark team stand ready and willing to help you achieve all your fitness goals.

Since you will be punching a heavy bag, you will need to protect your hands with boxing/MMA gloves. Feel free to bring your own or we have a variety of gloves available for purchase at the gym. Wear loose fitting, comfortable gym clothes. We guarantee you’re going to sweat. Therefore, shorts will probably be a good option. You will not be permitted to participate in a class unless you are wearing sneakers/tennis shoes. Please bring a towel and you will definitely need water or some type of sports drink. These are also available for purchase at the gym.

Each class is 1-hour in length and offers a total body workout. You will sweat, de-stress and enjoy exercising more than ever.
