Derek Rendleman II – Boxing Skills & Drills Coach

Boxing Skills & Drills Coach –

Hey there, I’m Derek Rendleman II, and I’m passionate about transforming lives through fitness. As a dedicated Personal Trainer and Boxing Coach at Self Made Training Facility Columbus, I’ve committed myself to helping individuals achieve their fitness goals and unleash their full potential.

With a specialized focus on weight loss, conditioning, and honing boxing skills and drills, I bring a holistic approach to fitness. My journey began over four years ago when I embarked on this incredible path. Being a certified personal trainer through the ISSA, I continually refine my expertise to offer top-notch guidance and support to my clients.

Beyond the gym, I’m a proud husband and father of four wonderful children. My family is my backbone, providing the inspiration and motivation that fuels my drive to make a difference in the lives of others.

Together with my amazing wife, Myicha, I co-operate KnockOut Self Doubt—a platform dedicated to empowering individuals to overcome mental barriers while embracing physical fitness. We believe that a strong mind and a strong body go hand-in-hand, and our mission is to guide people towards achieving both.

My coaching philosophy isn’t just about sets and reps; it’s about fostering a mindset of determination, resilience, and self-belief. Every session with me is crafted to not only challenge your body but also to cultivate the mental fortitude needed to conquer self-doubt and push beyond limits.

I understand that embarking on a fitness journey can be daunting, but rest assured, I’m here to support you every step of the way. Whether you’re looking to shed those extra pounds, improve your overall conditioning, or sharpen your boxing skills, I’ll tailor a program specifically designed to meet your needs and aspirations.

Join me in this transformative journey towards a healthier, stronger, and more confident version of yourself. Together, let’s knock out self-doubt and unlock the incredible potential within you.

Let’s train, let’s grow, and let’s conquer!
