Aerobic exercise best for belly fat reduction: Study

A new study has shown that the best type of exercise to burn unhealthy belly fat is aerobic exercise. The results showed that people who did aerobics for eight months lost about 2.5 square inches of belly fat, as measured on a CT scan. That's about 1.5 times as much as people who did a combination of aerobic exercise and weight lifting, and about 20 times as much as those who only lifted weights.
