The "Healthy Fitness Zone1"
The FITNESSGRAM uses criterion-referenced standards to evaluate fitness performance. The standards were established by The Cooper Institute to represent a level of fitness that offers some degree of protection against diseases that result from sedentary living.
While sit-ups can't "target" belly fat, what they can do is help you burn calories, strengthen your core and develop more muscle. Because muscle is more metabolically active than fat, the more muscle you have, the more calories you'll burn when you're at rest.

For each test area, the FITNESSGRAM uses the Healthy Fitness Zone (HFZ) to evaluate fitness performance. The performance goal for all test areas is the HFZ. Skinfold Measurements / Bioelectric Impedance Analyzer. percent body fat. Age.
