I’m Kourosh Hosseini, a former professional soccer player turned sports medicine specialist, corrective exercise coach, and personal trainer in Lake Forest, CA.

My path here started with an injury, not a classroom. A herniated disc nearly ended my career. I chose corrective movement over surgery, and it worked. Since then I treat pain as something to solve, not something to mask.

Today I run a private clinical office next to my gym. Deep tissue massage, cupping, and posture correction on one side, structured training on the other. Every plan starts with a real assessment, not a generic program.

Pro athlete. Then patient. Now coach.

  • 15+years in the field
  • 5+years as a professional soccer player
  • 6,000+members at the gym I managed
  • 50+trainers I've trained to get results

What I bring

I know performance from the inside.

More than 15 years in this field. Five-plus as a professional soccer player, then fitness manager at a gym with more than 6,000 members, where I trained over 50 trainers to get results for their own clients.

I know what it takes to compete, get hurt, and come back stronger.

I built Kur Athletx, my own coaching app, so online clients get the same structure and attention: daily tracking, video form checks, and a coach who reviews your progress every week.

What I believe

Five rules I coach by.

  1. Performance without recovery breaks down.
  2. Technique comes before intensity.
  3. Strength, mobility, and longevity progress together, not one at the expense of the others.
  4. Results should be measured, not just promised.
  5. The goal isn't a quick fix. It's a fix that lasts.
