Data on students' physical activity levels were obtained using a paper-based online IPAQ questionnaire. The results of this study indicated that the BMI categories for males were 37.5% underweight, 37.3% normal, 9.8% overweight, and 15.4% obese, while for females were 35.7% underweight, 46.4% normal, 9.3% overweight, and 8.6 obese. The findings in this study provided evidence that the BMI of high school students in Cilegon was in the normal or healthy weight category. However, in the BMI category, there were still many research subjects who were in the obese category. This was because the physical activities carried out by students were in a low category.
