Tummy fat is serious killer

Tummy fat is the most unhealthy because it's linked to heart disease. The more central the fat, the more it's laid down in the arteries. By just lifting weights twice a week for an hour, women can battle the buildup of tummy fat that often takes hold with aging, a new study suggests. And they don’t even need to diet. Weight training adds muscle mass which helps a woman moves faster and burns calories more efficiently.

"I think exercise is the fountain of youth," Dr. Rita Redberg said. "If it was a pill, everyone would be taking it."
