abs

hey guys i need some help with my abs. I can see my upper abs but i have this small pocket of fat covering the last 2 pacs..=( please advice on what i should do thanks =)

do exercises like hanging from a chin-up bar and, without swinging, slowly bring your knees to your chest and back down. You can also do that from a roman chair. Also do the '4 times abs' from this site. Good luck!
