John Xenakis

My name is John Xenakis, and I’m a NASM Certified Personal Trainer, fitness coach, speaker, and content creator based in Columbia, South Carolina.

At one point, I was approximately 45% body fat and struggling with my health, confidence, and overall quality of life. Through years of learning, trial and error, and a commitment to evidence-based nutrition and training, I reduced my body fat to under 15% while maintaining and building muscle. That transformation didn’t just change my physique—it changed my confidence, my mindset, and the direction of my life.

Today, I help others achieve sustainable fat loss, build muscle, and develop habits that support long-term success. While many fitness conversations focus on quick fixes, I enjoy discussing the practical strategies, mindset shifts, and behavioral changes that create lasting results.

One unique aspect of my journey is that I initially delayed going vegan for nearly two years because I believed it would hurt my strength, muscle mass, and athletic performance. At the time, strength was a major part of my identity, and I was convinced that a plant-based diet would hold me back. Eventually, I decided to test those beliefs for myself and discovered that many of my assumptions were wrong.

I’ve now been vegan for nearly 10 years while continuing to build muscle, maintain strength, and pursue my fitness goals. My experience allows me to speak not only about fitness and nutrition, but also about overcoming limiting beliefs, navigating major lifestyle changes, and aligning your actions with your values.

I enjoy discussing sustainable weight loss, muscle building, confidence, mindset, behavior change, calorie management, plant-based nutrition, vegan ethics, and the lessons I’ve learned from transforming my own health. I can also speak about how physical transformation impacts other areas of life, including self-confidence, relationships, career opportunities, and personal growth.

Whether your audience is interested in health, fitness, self-improvement, entrepreneurship, or veganism, I aim to provide practical advice, relatable experiences, and honest insights grounded in real-world results.
