About Us

We are Boston's premiere obstacle and personal training studio. We have an ever-growing number of obstacles designed by real American Ninja Warriors. Our courses are constantly changing and limited only by the imagination of our coaches and athletes. At Action Athletics, limitations are temporary and impossible is just a suggestion. Beginners, seasoned athletes, kids, American Ninja Warriors, and obstacle course racers all train at Action Athletics.
