The purpose of this study was to determine the correlation of BMI on postural balance. Methods: A sample of 30 male’s subjects took part in the study. All the 30 male volunteer were randomly divided into three groups according to their body mass index as Underweight (Group A), Normal (Group B), and Overweight (Group C) then two balance tests were carried out to evaluate the correlation between body mass index and postural balance. Results: showed that high body mass index (BMI) demands more displacements to maintain postural balance. Thus “High body mass index (BMI) effect the postural balance”. Conclusion: high body mass effects the postural balance
