Our Mission
We are SIGMA MARTIAL ARTS & FITNESS, founded with the mission to improve both mind and body through the martial arts, Sigma Martial Arts & Fitness provides the education and training necessary for a positive transformation in our students. Martial arts go far beyond the physical training of our practitioners -- we teach our students to value confidence and discipline. Discipline is a practice that is essential to the overall health of our students, and at Sigma Martial Arts, we ensure that this is coming from different practices which are upheld and honored at our studio. Located in Medford, Massachusetts, our martial arts instructors look forward to guiding our community in a practice that will span far beyond the walls of our studio.
The goal of Sigma Martial Arts is to improve “the whole of body and mind.” To do so, we teach a well-rounded martial arts program dedicated to strengthening both mind and body, physical and psychological, work and rest, with other services meant to enhance the student’s development in the martial arts. The Greek letter sigma (∑) is used in mathematics to denote the sum of an equation. The goal is to focus on the sum, or whole, individual as well as the whole family.
What People Are Saying
★★★★★
“I've been going here for almost a whole year, and I absolutely love the place. It's welcoming, fun, clean, and a great workout! The instructors are friendly and kind, they offer a lot of different classes, and it's great for both kids and adults. To me, it's a perfect middle ground between the extremes of super hardcore bro gyms that focus only on competition, and flakey programs that give you exercise but no real martial arts training.” — Alison E.
