Introducing the Marble Strength Team

Meet the fitness experts ready to help you achieve your fitness goals and your potential.

Our Founder

Joe Cosenza

Marble Strength was founded with the mission to build a healthier community in the Freehold/Jackson area by creating a consistent and successful path to creating lifelong sustainable habits. We want to help people feel better about themselves, to be able to play with their children/grand children and feel comfortable with saying I can and I will!

Since inception we have helped thousands of people get back on track and achieve their goals! Our expert coaches thrive on helping our members achieve their first pull up, be able to squat better, compete in a sport they never knew existed and seize the opportunity to build long lasting relationships.

At Marble Strength, we prioritize Coaching. In a group or personal setting. You want help to improve and to see results and we are there to guide you in the right direction. Hard work, discipline and consistency. That is Marble Strength.

Our gym combines every aspect of exercise science, ensuring that you get the results you want. We offer proven workouts to build energy and endurance. We combine that with sensible eating plans that help you hit that sweet spot where you lose fat while you gain muscle.

We want our gym to be a thriving like-minded community of fitness enthusiasts that support and encourage each other. We aim to do this by combining individual training with group classes of people at your level and coaches that understand your particular needs and goals.
