About Kolja

Kolja holds one of the most respected credentials in strength and conditioning.

The NSCA-CSCS, on top of an exercise physiology degree from Hofstra. A former college football player and U.S. Air Force veteran, he builds training around functional movement patterns that carry into everything you do.

Why train with Kolja, in Kolja’s words

“Growing up, I spent my time outside playing any sport offered, eventually playing college football. Afterward, I joined the United States Air Force. I have a background in weightlifting and prioritize functional movement patterns to improve overall performance and wellness.”

“Here am I! Send me.”Kolja’s favorite quote · Isaiah 6:8
The Standard

What it takes to coach at Redefine

Nobody trains clients at Redefine Fitness without passing a screening test, an in-person skill practical, and a written exam just to get hired, then testing out of a 30-day onboarding against our 100-page Training Master Guide. Every Thursday from 1-2 PM we close both gyms so the entire staff trains together, and every specialist sits annual exams on a tiered education ladder. We also created a New York State Department of Labor approved Fitness Specialist apprenticeship. Fitness is medicine, and this is what the standard behind it looks like.
