Our mission at CrossFit Long Island is to build a physically fit and capable community of dedicated members both young and old, and enable them to enhance and improve their lifestyle physically, mentally, and emotionally. We do this by embracing challenges, pushing our physical limits, and continually striving to be "better than yesterday". We learn new skills, master old skills, and break down barriers on a daily basis. Oh, and we have a helluva fun time doing it!
