Exercise Prescription for Optimum Health Benefits


Physical inactivity is now identified as the fourth leading risk factor for death globally, accounting for about 6% of the total deaths worldwide. Physical inactivity levels are rising globally, spanning all economic, educational and age strata.

Physical inactivity, i.e. lack of exercise, is estimated as the principal cause for approximately 21-25% of breast and colon cancer burden, 27% of diabetes and approximately 30% of coronary artery diseases (which can ultimately lead to heart attack).
