When it comes to walking, more is better

Reuters reports:

People who walk enough to meet or exceed physical activity recommendations may be less likely to die early than those who only walk a little, new research shows.

The American Heart Association (AHA) recommends adults be physically active for at least two and a half hours per week. Previous research has shown exercising more than that may bring extra benefits.

"An important question left to be answered is how much walking is beneficial," study author Paul Williams, from the Lawrence Berkeley National Laboratory in Berkeley, California, said.

He analyzed data from 42,000 mostly middle-aged people who enrolled in the National Walkers' Health Study between 1998 and 2001. They had all subscribed to a walking magazine or attended walking events before the study.
