Get started now and find out how you can be healthier, happier and more confident with Black Belt World training! . Our members tell us that they feel our school is more of an institution of self-improvement, physically and mentally, rather than “just” a gym or some “activity”. I pride myself on helping our adult members safely build muscle, quickly burn fat, gain flexibility and release stress in a FUN, positive and injury free environment! And for the children, parents all over the Somerville, Piscataway, and Somerset area give my martial arts classes credit for increasing their child’s ability to focus, building their self-esteem and igniting a passion for self improvement they never would have expected.
