About Us

CrossFit Mariner Square (CFMS) opened its doors on August 1st, 2011. The box is a 3,200 square foot facility located within Mariner Square Athletic Club (MSAC). CFMS is constantly striving to provide the best CrossFit experience to its members. The trainers look at every member, catering and molding workouts to each individual. Community is very important to us, and we love group outings, picnics, and team competitions.

CrossFit Kids is coming to CFMS! The kids program will be up and running within the next few months. We will provide updates as the start date gets closer.

CrossFit Kids

CrossFit Kids is starting July 6th!
CrossFit Kids combines gymnastics, body-weight calisthenics, and weightlifting to help kids develop across 10 general physical skills: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, accuracy, balance, and coordination. There is additional focus on elements that encourage bone density and vestibular system development. Children and teens have a great opportunity to maximize their physical skills when exposed to this stimulus during years of peak development. The elements are combined to keep children engaged and entertained, while teaching them proper movement mechanics. CrossFit Kids is a program that pairs fitness and fun to create a lifelong love of health and fitness.
