Studies show that in the vast majority of cases, more exercise is better.
There is a 30 percent reduction in mortality in individuals who exercise one hour a week compared to sedentary individuals.
People who exercise three hours a week lower their risk of death by another 10 percent.
Those who engage in 150 minutes of moderate or 75 minutes of vigorous exercise a week and weight train twice a week will reduce their risk of premature death by 50 percent.
