Many adults may be meeting experts’ 30 minute recommendation on exercise if all types of activity, from work and play, are counted, a study of Swedish adults hints. Researchers found that among 1,470 adults ages 18 to 74, nearly two-thirds were meeting the goal of moderate physical activity on most days of the week. Getting more people off the couch, they say, will take broad “social-ecological approaches” which essentially means making it easier for people to be active in their daily lives. That could include making it simpler for people to walk or bike – by building more sidewalks, for instance – or giving them more parks and recreational areas.
