About Us

Meet
Ivan Birkas

Founder of Advanced Fitness Protocol | HEAD COACH | Husband | Dad

Born and raised in Serbia, Ivan Birkas was shaped by discipline, hard work, and integrity. Though he earned a degree in criminal defense law, his true passion was always movement — from martial arts and kayaking to the gym, where he found his lifelong calling.

Ivan discovered fitness over 20 years ago. What began as curiosity became obsession, then a career. Friends came to him for advice long before he called himself a coach. In 2014, he left behind stability and a legal career to start over in the U.S., chasing purpose — not comfort.

No shortcuts. No hype. Ivan built his coaching business, Advanced Fitness Protocol, from the ground up in Boca Raton. Today, he leads a small, elite team that delivers over 70 personal training sessions weekly across 14 locations — all built on honesty, science, and real results.

Ivan specializes in helping busy men and women build strong, confident bodies—not through extreme diets or flashy gimmicks, but with sustainable systems that fit their lives. He understands the pressure of being a provider, business owner, and parent—because he lives it, too.

His motto: “Nobody is coming to save you — do it for yourself.”

And he’s here to help you do exactly that.

PERSONAL TRAINER

I started my fitness journey with a strong background in basketball and athletic training, where I learned the value of discipline, hard work, and performance. Over time, I discovered a deep passion for bodybuilding and the art of transforming both body and mind. Learning from top mentors around me, I gained knowledge and experience that shaped the way I approach training and lifestyle

This passion grew into a purpose—helping others achieve the same breakthroughs I experienced. I understand the challenges of building muscle, losing fat, and staying consistent, and I’m committed to guiding clients every step of the way.

As a NASM Certified Personal Trainer, I blend my athletic roots with bodybuilding expertise.

My mission is simple: to help you unlock your potential and build the best version of yourself.

My coaches make every session fun while still challenging, keeping me motivated for well over a year. Training has boosted my confidence, my physical capabilities, and my overall wellbeing, and I couldn’t be more thankful for how well this program helped me level up.

I’ve been working with Ivan for almost 3 years now, and I feel very lucky to have found him as a trainer. When I first started training, I worked with a number of people who really didn’t know what they were doing and it was immediately different with Ivan. He’s extremely knowledgeable about training, body mechanics, nutrition, etc. I’ve had multiple unrelated injuries, and he has always been able to figure out a way to work around them so that I’m not hurting myself more, but I’m still seeing results. He is also a great guy and enjoyable to work with, even though he’s making me really work! I’ve gotten to become friends with him personally and I trust him implicitly, which is not necessarily common in this industry. If you’re lucky enough to get to work with Ivan you won’t regret it.

When I first started training with Ivan, I weighed 225 pounds. Now I’m under 200 and, for the first time in my life, I’m actually muscular — something I never thought I could be. What’s even crazier is that the whole process was fun. I expected it to be torture, but Ivan’s personality, motivation, and energy made every session something I looked forward to. He pushed me without ever making me feel overwhelmed, and he believed in me when I didn’t believe in myself. Today, I feel better about my body and my health than I ever have, and I owe that to Ivan.

I’ve been training with Ivancito for the last three years or so and I couldn’t ask for a better personal trainer. He knows his stuff inside out, always makes sure workouts are safe and effective, and somehow manages to push me just the right amount. He’s strict in a good way – the kind that keeps you motivated – but at the same time super flexible and always willing to adjust sessions to fit my needs or energy levels.

What I like most is that Ivan genuinely cares about helping you get to your goals, whatever they are. He’s supportive, encouraging, and just a really nice guy to spend time with while training. He’ll challenge you, cheer you on and sometimes scream.

Haha but he never gives up on getting you where you want to be.

Ivan has truly changed my life. For years I struggled with my weight going up and down and never felt toned or confident in my body. Working with him these past three years has completely shifted not only how I look, but also how I feel about myself. I’m stronger, healthier, and finally consistent thanks to his guidance and support. Ivan isn’t just a coach—he’s someone who genuinely cares and pushes you to become your best.
