Evolution BJJ in Lowell hands down is the best place to train JiuJitsu. Whether you have ambitions to train for self defense, or as a hobby, this is definitely the place to go. The instructors are great and patient with each students improvement skills. The group of people who train here are like a unique brotherhood. I have been training for a year and half now and feel comfortable protecting myself. They conduct amazing kids and adult classes. Great place to stay in shape. !!!!
