Being fit lowers the risk of having heart attacks and increases survival rates in those with coronary artery disease, according to researchers at the John Hopkins University School of Medicine in the US. Meanwhile, an Austrian study showed that a mere three weeks of exercise and a healthy diet produced positive changes in middle aged men with metabolic syndrome, one of the causes of heart disease.
Researchers from the Harvard School of Public Health and the University of Southern Denmark have found that three and a half hours of weight training exercises each week leads to a dramatic decrease in risk of type 2 diabetes among women.

Even when it comes to depression, exercise can work as well as any antidepressant, say experts. A recent systematic review published in the Journal of Science in Medicine and Sport found that regular exercise is likely to be effective in the treatment of many depression symptoms.
