According to a large-scale study published Monday in the American Heart Association's journal Circulation, performing far more exercise than currently recommended reduces mortality risks.

People who exercised two to four times more than the American Heart Association's weekly minimum recommendation of 150 minutes of moderate activity had a reduction in mortality risk of 26% to 31%.

The study looked at the activity of 100,000 adults over the course of 30 years.

People who did 150 minutes of moderate exercise weekly had a 20% reduction in mortality risk, while those who did 75 minutes had a 19% reduction.

When performing between 150 and 300 minutes of vigorous exercise weekly or between 300 and 600 minutes of moderate activity, the maximum benefit in mortality reduction occurs.

The study found no link between exercising more than four times the recommended guidelines for moderate and vigorous activity and cardiovascular health effects.

Regular exercise can prolong your life. A meta-analysis of 16 studies published in the British Journal of Sports Medicine found that 30 to 60 minutes of weekly strength exercise is associated with a 15% decrease in all-cause mortality. According to a study published in the Journal of the American Medical Association, there may be a link between lower muscle mass and cognitive decline in old people.

The lack of association between the highest levels of exercise and harmful health risk may reduce the concerns about the potential harmful effect of engaging in high levels of physical activity.

A study suggests that lower muscle mass is linked to a decline in cognitive function.

Studies say strength training can help you live longer.
