Physical inactivity is the biggest health problem of 21st century. Exercise is medicine and gives many health benefits if it is prescribed in form of frequency- intensity-time-type (FITT) that reverses aging process in many ways & add years to life. Haskell and Pollock US Department of Health and Human Services gave Classification of physical activity intensity based on physical activity lasting up to 60 minutes. Consent was taken from 80 subjects and their coaches for (10 subjects for each physical activity) at random those who cleared physical activity readiness questionnaire to estimate intensity by noting percentage of estimated maximum heart rate. (MHR = 220 - age in years); for that ;heart rate was observed by radial pulse within ten seconds then multiplied by six to get beat per minute just at the end of one hour of different type of physical activity. In my observation intensity range in form of percentage of maximum heart rate (MHR) for slow walking was 44.98% (light intensity range up to 49% of MHR), for volleyball 53.94%, for yoga 54.80%, for dance 56.78%, for brisk walking 64.98% (moderate intensity range 50-69% of MHR), for basketball 76.73%, for football 77.31%, for jogging 85.44% (hard intensity range 70-100% of MHR).
