A new study suggests that "if you don't work hard when you're young, you'll feel sad when you're old." Having a strong physique in your 20s can significantly reduce the risk of death in middle age. It can be seen that exercise should be done early. Researchers have found that people who can persist on treadmills for longer periods of time when they are young have a lower chance of dying from diseases such as cancer and heart disease 25 years later.

The same goes for marathons, which are a long-term endurance exercise that brings many benefits to the heart and vascular system. One of the changes caused by extensive endurance training to the heart is enlargement or hypertrophy of the heart. In different heart diseases, hypertrophy is pathological, but through endurance training, hypertrophy is actually beneficial. Through exercise, the heart expands and gains more myocardial tissue, allowing it to deliver more oxygen rich blood to the muscles during exercise to support your movement. An increase in testing time every minute implies a 15% reduction in the risk of death, which is not affected by weight, cholesterol content, blood pressure, and blood sugar levels. This is a description by Murthy's team in the Internal Medicine issue of the Journal of the American Medical Association (JAMA). 15% chance of death. " The team conducted a long-term heart health study on 4800 volunteers. Back in 1985 and 1986, when the volunteers were between the ages of 18 and 30, they were assigned to undergo cholesterol testing, hypertension and blood glucose testing, weight recording, and then treadmill testing.

"Fitness never ends," "The healthier the body, the lower the risk of developing cardiovascular disease." Every minute of testing time is reduced, and his/her chance of death increases by 21% after 25 years, while the chance of developing heart disease increases by 20%.
