More American adults are walking regularly, but less than half of them exercise enough to improve their health, according to a study from the Centers for Disease Control and Prevention.
It found that 62 percent of adults walk 10 minutes or more a week, up from 55.7 percent in 2005. But only 48 percent of adults exercise enough to improve their health, which was up from 42.1 percent in 2005, the CDC said.
The agency recommends at least 150 minutes per week of aerobic exercise, such as brisk walking, which can lower the risk of heart disease, stroke, type 2 diabetes, depression and some forms of cancer.
