Moving from No to Go, 2018 guidelines for exercise

“Probably the most important message from the 2018 guidelines is that the greatest health benefits accrue by moving from no, to even small amounts of, physical activity, especially if that activity is of moderate (eg, brisk walking) or vigorous (eg, jogging and running) intensity. Multiple studies demonstrate that the steepest reduction in disease risk, such as for coronary heart disease, occurs at the lowest levels of physical activity.² Patients need to understand that even small amounts of physical activity are beneficial and that reductions in the risk of disease and disability occur by simply getting moving. The evidence demonstrates that adults obtain the maximal benefits of physical activity by regularly performing 150 to 300 minutes per week of moderate-intensity or 75 to 150 minutes per week of vigorous-intensity activity or an equivalent combination of moderate- and vigorous-intensity aerobic activity. These levels of activity are possible for most healthy people.”
