Exercise several times a week.
A routine that includes at least 150 minutes of moderate-intensity exercise per week—brisk walking, ballroom dancing, or gardening, for example—or 75 minutes per week of vigorous activity, such as jogging, aerobic dancing, or jumping rope, is one of the targets for achieving ideal heart health, according to the AHA.
Still, it's not always easy to start an exercise regimen if you've been sedentary for a long time. A good general rule of thumb: "If you're doing nothing, do something, and if you're doing something, do more," Yancy says. Then, gradually lengthen your exercise routine until you meet the recommended targets.
