George Rosenberg
Athlete’s eye. Diet-first coaching. Mount Sinai shift lead.
George leads the Mount Sinai floor with an athlete’s standard.
George came to fitness two ways at once: through an athletic background, and through watching illness move through his own family. That combination made health personal early, and it’s why he does this work.
He chose Redefine because the people here actually care about health — not a given in this industry. He runs the Mount Sinai floor on one firm belief: how you eat matters just as much as how you train.
Who George works best with
Anyone trying to improve, from any starting point.
One of his clients dropped a pant size and, more than that, felt confident about how they looked again.
What most people get wrong
How crucial the quality of your diet is. You can’t out-train it, and most people badly underrate how much it matters.
In George’s words
“Everyone I work with is trying to improve, and the thing most people underrate is how much the quality of their diet matters.”
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.
