All exercise carries some risk of injury, cardiovascular problems, and even death, but low-intensity exercise has a very low risk. In the USA, there is approximately one exercise-related death for every 15 000 to 20 000 people. Many more die from diseases caused by inactivity than from overactivity. However, risks increase with the intensity of exercise, and some forms of exercise are unsuitable for certain groups of people. Those with doubts about their health status should consult a medical practitioner before starting an exercise programme. See also contraindicated and sudden death.
