The current recommendation is that every person should get 150 minutes weekly of moderate-to-vigorous intensity physical activity (MVPA) to reduce the risk of all-cause mortality. Analysis of 122,000 older individuals from 9 cohort studies followed for an average of 10 years found even low-dose MVPA reduced the risk of all-cause mortality by 22% compared to inactivity. Medium-dose and high-dose MVPA further reduced the mortality by 28% and 35%, respectively.
PositiveTip: Any exercise is better than none. Health benefits accrue with any amount of physical activity.
