My name is Ronnell Leftwich, also known as Kilo Nellz—a fitness professional with over a decade of experience dedicated to strength, performance, and transformation.

My journey into the Iron Game started early. Growing up with a father who was active in the bodybuilding world throughout the early 90s, I was introduced to the discipline, grit, and focus that this lifestyle demands. From a young age, I didn’t just learn how to train—I learned how to live it.

Over the years, I’ve taken that foundation and built a career rooted in helping others unlock their full potential. For more than ten years, I’ve worked as a personal trainer, guiding individuals through every stage of their fitness journey—whether the goal is strength, fat loss, body composition, or high-performance training.

As a world-class powerlifter with eight years of competitive experience and a Top 5 global ranking, I bring elite-level expertise backed by real-world results. My training philosophy is simple: combine proven science with unmatched intensity to create lasting change. I specialize in:

• Strength training & powerlifting

• Muscle building & hypertrophy

• Fat loss & body composition

• Athletic performance enhancement

At KiloNellzTraining.com, you’re not just getting a coach—you’re joining a movement. This is where education meets execution, and where everyday people learn to train like champions.

Welcome to the next chapter of your fitness journey. Let’s build something heavy—together.

I am proudly certified as a Personal Trainer by the International Sports Sciences Association (ISSA), continuing to uphold the highest standards in coaching and client care.
