Why Islip CrossFit 

Our goal at Islip CrossFit is to cultivate a community that transforms lives by providing high-intensity, functional fitness training in order to live happier and healthier. We believe in working hard to get great results, but we also believe that having fun during this process is essential!


CrossFit begins with a belief in fitness. Its aim is to forge a broad and inclusive fitness system. We strive each day to build a program that will best prepare trainees for any physical contingency — not only for the unknown, but also for the unknowable!

CrossFit Kids is a method for teaching Greg Glassman’s CrossFit to children ages 3-18. Based on the principle of Mechanics, Consistency and then Intensity, CrossFit Kids emphasizes good movement throughout childhood and adolescence. Consistently good mechanics translates to physical literacy, enhanced sports performance and fewer sports injuries for kids.
