About Sebastian
Most people think martial arts is just for fighters.
I used to think the same thing.
Then I stepped into my first Jeet Kune Do class and everything changed. The technique. The discipline. The way your whole body has to work together. I was hooked.
That was over 7 years ago. Since then I've coached at gyms across the Chicago / Lombard area, trained Muay Thai in Thailand, and built programs that have helped everyday people get stronger, move better, and actually enjoy training.
That's what MMAPOP is built on.
Who I Work With
I coach everyday people who want to feel stronger, move better, and actually enjoy training.
Whether you've never touched a heavy bag or you've been training for years — if you're ready to show up and put in the work, I'll meet you exactly where you are.
No experience required. Just the willingness to start.
My Background
My martial arts journey started with Jeet Kune Do, where I earned my certification and fell in love with the science of striking. That led me to Muay Thai — and eventually four months training in Thailand where everything leveled up. Along the way I picked up Wing Chun, Silat, and Arnis, and added BJJ to round out my grappling base.
From there I went deeper into the fitness side — strength training, weight loss programming, and general conditioning. I wanted to build programs that actually worked for everyday people, not just athletes. That's where everything came together.
Over the years I've coached at multiple gyms across the Chicago / Lombard area, including UFC Gym Yorktown, building experience across different training environments and client goals.
Before coaching full time I worked as a CNC machine operator. That background taught me precision, patience, and how to break complex things into simple repeatable steps — skills I use every single day as a coach.
Seven years ago I made the switch. I haven't looked back.
