Structured, evidence-based, built for real progress.
George runs the evening floor at Mount Sinai.
His sessions are structured, evidence-based, and built for people who want a clear path from where they are to where they want to be.
Why train with George, in George’s words
“I don’t just give workouts. I build structured, results-driven plans tailored to your body, goals, and lifestyle. Using evidence-based training, smart programming, and strategic nutrition guidance, I help you build muscle, increase strength, and develop habits that last. If you’re ready to train with purpose, discipline, and a clear path to real progress, I’m ready to lead you there.”
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.
Start with a complimentary consultation. Bring your history. We will build the plan.
