This study will be done to answer the following question:

Do brain gym exercises have an effect on risk of fall, static balance, dynamic balance and risk of fall and quality of life in obese subjects?

Obesity has now become a severe and inescapable worry for people of all generations. Obesity is associated with an excessive or inappropriate fat build-up that poses a health concern. A BMI of 25 or above is considered to be overweight, while a BMI of 30 is classified as obese. In 2017, nearly 4 million individuals died as a direct result of being overweight and obese, according to the global burden of sickness report. Postural equilibrium is required for us to function normally in our daily lives. The ability to manage the center of mass inside the base of support, which serves to maintain the body in balance, is characterized as equilibrium. Balance is described as the process of maintaining the body center of gravity within its support base, which necessitates regular modifications given by muscle activity and joint alignment . 1. Thirty-two obese subjects from both gender with age ranging from 18-50 years old . And BMI ≥ 30 kg/m2. They will be selected from faculty of physical therapy Kafr Elshikh university Group A (exprimental group): 16 subjects received brain gym exercises for 15-30 minutes per day, three times a week, for eight consecutive weeks . And traditional treatment in form of balance training included standing on one leg, standing in tandem mode, walking in a tandem mode (one foot in front of the other), walking on toes and heels, side walk, standing while one upper extremity and the opposite lower extremity were up, rotating the head from side to side, walking backwards for four steps, and shifting weight from one foot to the other. Periodic exercises were frequently performed for 45 min for 3 sessions per week for 8 weeks Group B (control group): 16 subjects will receive traditional treatment in form of balance training included standing on one leg, standing in tandem mode, walking in a tandem mode (one foot in front of the other), walking on toes and heels, side walk, standing while one upper extremity and the opposite lower extremity were up, rotating the head from side to side, walking backwards for four steps, and shifting weight from one foot to the other. Periodic exercises were frequently performed for 45 min for 3 sessions per week for 8 weeks

Inclusion Criteria:1- Obese subjects from both gender age range from 18-50 years old (Cruz-Gomez et al., 2021) 2- BMI ≥ 30 kg/m2
