John Bayza

Started as the skinny kid who wanted to get strong. Now he makes the gym feel doable for people who dread it.

About John

John remembers what it is like to walk into a gym and not know where to start.

John started lifting as a sophomore in high school. He was a skinny kid who wanted size and strength, and he has been at it ever since. What began as a personal goal turned into wanting to coach other people through the same first steps.

He chose Redefine because it sits in the space between physical therapy and a regular gym: individualized programs for people with real histories, which a regular gym cannot offer.

Who John works best with

People who are intimidated by gyms. John gives clear guidance and a personalized plan, and builds confidence one session at a time until the fear is gone and the habit is there.

What most people get wrong

Piling on exercises that all do the same job. John programs by what each muscle actually does. For the quadriceps, that means one pressing movement you enjoy plus a leg extension, not a squat and a leg press doing the same work twice.

In John’s words

“I value the establishment of a middle ground between physical therapy and a regular gym.”

“I want to help others in their journeys.”
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.
