Personal Trainer — San Diego

Building your
best body.

Thirty years, eight magazine covers, and one promise: the truth about training and food — from a coach who has lived it.

John Turk, founder of Fearless Fitness
Meet John Turk

30 years. One promise: the truth.

“I understand the power food holds over us — because I’ve lived it.”

Collegiate Mr. Illinois, international cover model, and a former Chicago-area police fitness instructor. John has trained San Diego for three decades — and he’s open about his own battle with binge eating, because it’s the reason he understands the fight most trainers never talk about.

Bachelor’s in Exercise Physiology, certifications in the ACSM and NASM (corrective exercise specialist), NSCA-CSCS, and myo-fascial release specialist. Real credentials behind real results.

And yes — that Sub-Zero. John was the actor behind Sub-Zero and Shang Tsung in Mortal Kombat 3 and every masked ninja in Ultimate Mortal Kombat 3. The Sub-Zero story →

I came to John with a specific goal — to be ready to compete in my first bodybuilding contest at age 37. He got me there. The results speak for themselves.

For three years I dieted, worked out, and went through different trainers — and gained weight, with a severe thyroid problem. John finally got me results nobody else could.

After a lot of research and a long phone call, I knew John was the right trainer for me. I’ve worked with trainers before — none came close to his knowledge or the way he builds a program.

John Turk is an amazing personal trainer. I started with him just after turning 30, about 20 lbs over my ideal weight. Everything he does is calculated, organized, and done for a specific reason.
