Miles for Your Mood

Need a body-image boost? Tack some extra time onto your next walk.

In a pilot study by researchers at the University of North Carolina Greensboro, researchers spent six months tracking the progress of young overweight women who exercised either 30 or 60 minutes a day, five days a week. Over the course of the study, the hour-long exercisers reported improvements in their feelings toward their bodies that were four times greater than the improvements experienced by the half-hour group. This finding jibes with the recommendations from the National Academy of Sciences, which recommends that everyone aim for 60 minutes of exercise each day for better overall health. Ready, set, walk!
