Q9: How often should I train abs?

Some writers recommend doing abs at every workout. Others recommend doing them however often you do anything else in other words treating them as you would any other body part. Health For Life's Legendary Abs recommends three or four times a week.

Since most people want good abdominal tone more than freaky abdominal size, it probably makes sense to exercise the abs with lower intensity and more frequently, rather than with high intensity and less frequently.
