Who Is Justin Cox

Not Your
Average Coach.

I'm a former U.S. Marine who spent 8 years learning that discipline, relentless systems, and accountability are the only things that produce real results. When I left the military, I turned that exact mindset toward fitness and never looked back.

I've competed on national and world stages, trained hundreds of clients across four continents, been voted one of the Top 10 Personal Trainers in San Diego, and featured in local press. Everything I've built stands on one principle: no fluff, just results.

I now operate out of Bangkok, Thailand — coaching clients remotely worldwide. My system is built around your reality: your schedule, your food environment, your goals, your life.

The Journey

How I Got Here.
