Merz Built Fitness in Linden, NJ
Who We Are

More Than A Gym

Merz Built Fitness is a training space in Linden, New Jersey. It was started by Billy Merz Jr., an IFBB Pro and certified trainer, along with his wife Joanna, because they wanted a room that felt less like a franchise and more like somewhere that knows your name.

What We Are Going For

The idea is simple. Give people who take training seriously a place to work without crowds, without waiting on equipment, and without feeling watched. From the first visit the aim is to hand you the room, the standard, and enough support that you are still here in month six.
