Pushing yourself really hard is NOT the only way to make a workout count. A new study from Pennsylvania State University shows that middle-aged women get more of the positive benefits (such as an energy and mood boost) from less intense activity.
"Moderate exercise like brisk walking is more pleasant, especially if you're a newbie," says study author Steriani Elavsky, assistant professor of kinesiology. "You'll be more likely to stick with it." Make sure you can carry on a conversation while moving.
