Private Training Studio · Linden, NJ
Built Different.
Built Together.
Merz Built Fitness is a private training facility on West Saint Georges Avenue, founded by IFBB Pro and certified trainer Billy Merz Jr. and his wife Joanna. Real coaching, real programming, and a room where nobody is waiting on a machine.

The Studio
A private room built for work.
One floor, everything you need, and never a line. The studio was set up for people who want to train seriously without a nightclub soundtrack or a queue for the squat rack.
Cardio floor
Machines for conditioning, warm ups and finishers, available whenever your session or your schedule calls for it.
Strength machines
Selectorized work for isolation, volume and the days when loading a bar is not the smart call.
24/7 fob access
Members get their own key fob. Five in the morning before work or ten at night after the kids are down, the door opens.
Training
Coaching that is actually written for you.
Every plan starts with where you are now, what your week really looks like, and what you are trying to build. Nothing here is pulled off a template.
“Commercial gyms are built for memberships. We are built for transformation.”
One on one personal training
Private sessions with a certified coach. Movement gets assessed, technique gets corrected, and the programming moves as you do. Best for anyone who wants direct attention and a plan that adjusts week to week.
Semi private sessions
Train alongside a partner or a small group under the same coach’s eye. You keep the individual programming and pick up the accountability that comes with training next to someone.
Open gym access
Members train on their own schedule with 24/7 fob access. Come in for a coached session, then run your other days independently in the same room.
What We Stand On
Four things we do not bend on.
Merz Built Fitness was founded with one mission: to create a private training space where performance, community and consistency come together to empower every member.
Community first
We are a family, not a facility. Members know each other’s names and notice when someone goes missing for a week.
Accountability always
Support does not stop when the session ends. Progress gets tracked and the follow up is real.
Integrity in coaching
Certified, experienced coaches who care about doing it right, including telling you when to back off.
Results driven systems
Science based method, personal attention. Functional strength and proper movement over random workouts.
Membership
Simple access, no small print.
Month to month or yearly, both with your own 24/7 key fob. No contracts and no cancellation fees, either way.

Personal training and semi private coaching are priced separately from membership. The team walks through options in person at the studio, since the right package depends on how many sessions a week actually fit your schedule.
The Team
Who you will be training with.
A small coaching staff on purpose. You will not be handed off to a different trainer every month.
Billy Merz Jr.
Founder, CEO & Head Trainer
IFBB Pro and certified personal trainer. Billy co-founded Merz Built to create a space where training, community and consistency come together in a supportive, no-ego environment.
Joanna Merz
Co-Owner
Co-founder alongside Billy. Joanna keeps the studio running behind the scenes and is a large part of why the room feels like a community rather than a facility.
Krishna Mansukhani
Personal Trainer
Coaches one on one and semi private sessions at the studio, working with members on movement quality, functional strength and staying consistent week to week.
