Jin Chen
New York State powerlifting record holder. He will get you strong.
Jin trains a full range of clients at Stony Brook — and competes in powerlifting at the national and world level.
Jin got into training tired of being the kid picked last in gym class. He answered it with strength. Today he holds every drug-tested New York State powerlifting record in the 52 kg class — squat, bench, deadlift, and total — and he is chasing a national deadlift record that has stood since 2019, having already pulled 480+ lb in training. He started out coaching combat-sport athletes — wrestlers, boxers, and MMA fighters — and now works with clients of every kind.
His first client at Redefine was 6’4”, in his 60s, using both a cane and a walker. Ten months of consistent training later he had dropped 60-plus pounds, ditched the cane, and could squat to full depth without falling — and moved to Florida to play golf.
Why train with Jin, in Jin’s words
“You don’t have to force your own goals or training style on a client. I like variety — it keeps training from getting stale — but the program is built around you, not me. I have broken bones in handball, wrestling, and boxing, and come back stronger every time. I will get you there too.”
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.
