Crossfit Kids

The CFKB Kids extends the benefits of a General Physical Preparedness (GPP) program to the youth population of Clinton Hills, Prospect Heights and Crown Heights.  Our certified CrossFit Kids Instructorswill provide a core curriculum in strength and conditioning that extends beyond the time spent in the gym.  We share our love for health and fitness in daily life, and teach foundational movement patterns that prepares youths for the unknown and the unknowable.

Our classes make strong use of play and fun as applied to fitness.  The program will be based on safe and proven movements within CrossFit’s teaching principles of mechanics, consistency and intensity; athletes are taught sound mechanics for movement, and only when they have shown that they can consistently demonstrate sound movement will intensity be applied to the exercise regimen. Consistently good mechanics translates to physical literacy, enhanced sports performance and fewer sports injuries for kids. Not only that, a vast body of research indicates that exercise is beneficial to cognitive function, which means consistent adherence to the program can have a positive impact on children’s academic achievement.  We will run, jump, skip rope; we throw, squat, and pick things up.  We play games and we learn new skills.  Your child will always learn a new movement, apply that new movement in a work out, play a game, and have fun!


Competition TRAINING

For athletes that are looking for that competitive edge, our competition classes meet twice weekly to push the boundaries of comfort. Workouts are generally an 90 minutes and focus on more intense weightlifting and longer conditioning. We recommend that you only participate in the Competition classes if you have at least a year of experience with regular CrossFit classes.
