Introduction: The rising prevalence of chronic diseases in India is partially attributable to factors such as decreased physical activity and fitness levels. With this in mind, the present study was conceived with the intention of determining the extent to which BMI is correlated with different levels of leisure-time activity.

Method: The total sample included two thousand two hundred and ten (N=2210) subjects, of which eight hundred and five (N=805) were from the government and fourteen hundred and five (N=1405) were from the general population. All of the subjects for this study were chosen using a random sampling technique.

Results: The findings showed that there were substantial variances throughout the group, with the exception of those who reported moderate weekly activities. According to the findings of this research, increasing the amount of time spent on physical activities during free time leads to a larger overall engagement by school students in organised physical activity as well as an increased amount of physical activity overall.

Conclusion: We can draw the conclusion that increased physical activities during leisure time leads to greater overall participation by school children in structured physical activity. In today's lifestyle, it is very important to involve the youth in physical activities while they are engaged in their leisure time.
