​We Are Boston's Premiere Obstacle and Personal Training Gym


​​Action Athletics is the proud training home of many athletes seen on the hit TV Show:  "American Ninja Warrior". 

Local stars like Casey Rothschild, Alex Goodwin, Conner Claffey,  Paulina Sterpe, and Josh Shriber as well as All-Star competitors like Jon "The Giant" Alexis, Jesse "Flex" Labreck, Allyssa Beird, and more helped build us into one of the country's finest obstacle training facilities. 

​With an ever-growing number of innovative obstacles and endless configurations, Action Athletics serves as a fun and challenging alternative to the conventional concept of fitness for the whole family.
