Teachers' health habits can have an impact on their students. Despite this, few studies have been conducted to investigate teacher physical activity and its relationship to life satisfaction. The prevalence of obesity has steadily increased over the years. Among both genders, the age-adjusted prevalence of being overweight or obese is higher among Omani participants across time. This study looks into how physical activity relates to life satisfaction among Oman's teachers. Some 671 teachers (40.3% male; 59.7% female) aged 20-50 years took part in the survey. Participants were recruited using a Google form survey. SPSS statistical tools were used to analyse the collected data. According to the findings, Physical Activity has a significant positive correlation with life satisfaction. The findings also revealed that gender influenced Omani teacher life satisfaction, with female teachers having higher life satisfaction than males. This study found no significant differences in life satisfaction based on age or Body Mass Index (BMI). This study was intended for use in public schools. More research can be conducted in both private and public schools. In sum, health promotion professionals might develop plans to improve employee health status if they had a better grasp of impact of factors associated with physical activity participation. As a result, there will be improvement in worker life satisfaction, which is considered to be a cognitive component of subjective well-being.
