The FITNESSGRAM physical fitness assessment is based not on athletic ability, but on good health. No matter what your children grow up to become, they will live happier, more productive lives if they are healthy--and physical fitness is vital to overall health. FITNESSGRAM provides accurate and reliable information about your child's level of physical fitness. The FITNESSGRAM test (and report) includes a number of different assessments because fitness has multiple components. Some kids may have good muscular fitness but need improvement on aerobic fitness. By having a complete report, you (and your child) will know more about their overall level of physical condition and how it can be improved.
