(Newser) – San Francisco has narrowly edged out Seattle for the distinction of being America's fittest big city, says a new study released by the American College of Sports Medicine. Judging 16 large metropolitan areas on factors ranging from exercise frequency and fruit intake to the availability of parks and public transportation, the study put Los Angeles near the bottom, reports USA Today.

"Cities can take this information and use it to improve the quality of life for their residents," says a fitness professor. Adults, he says, should be doing aerobic activity five days a week, and strength training twice weekly.
