What we do

The Training Lab is a place where you stop exercising and start training. We train hard and train smart.  Fitness in my perspective is the ability to perform a task.  Whether that’s to run a half marathon, complete a triathlon or OCR race, simply lose weight or just be a better version of yourself.  We’ll also provide unparalleled Personal Training, for a person looking to take their training to the next level with specific goals in mind or simply someone that wants to hone their movement skills in an environment besides a class setting.

Fitness is not defined by a set of standards but by the individual. However, we believe everyone should have a basic baseline to work off of. We we will work toward providing everyone with that baseline which will help you achieve your goals. In becoming part of our community, we will instill a greater awareness of not only the capacity of your body but also your mental tenacity. We believe awareness of body movement will not only help you unlock your true potential but that it will also lead to healthier decisions, relationships and lives.  This is not a business that will only value transactions, rather we are a community that elevates, cultivates and empowers people.

"I want to give everyone the tools they need to excel!"



Ruben Belliard


Ruben Belliard, founder of The Training Lab, grew up on the Lower East Side of New York City. Seeking a more active lifestyle and new surroundings, he joined the Marine Corps and served from 1997-2004 as an infantry rifleman, Instructor at The Basic School in Quantico, VA and overseas in Operation Iraqi Freedom.

After the Marines, Ruben decided to follow his passion and followed a career in the fitness industry in Manhattan. He quickly learned in the Marines that you are capable of so much more than you think if you just try, and applies this to his personal daily lifestyle and client training. He’s competed in Brazilian Jiu-Jitsu at a national level, Ironman, all distance triathlons, cycling, running and obstacle races.

In 2008, Ruben started Warrior Fitness Boot Camp which he owned and operated until 2016. Throughout his career he saw how his clients’ interest in fitness evolved and the struggles they had when trying to make a change. He created The Training Lab to help people build a foundation that would allow you to do anything you wanted. He’s educating and breaking predetermined assumptions people have about their capacities with inspiration from his military training – at The Training Lab you train hard and train smart!
