I need help with an ab routine. Like many other people, I'd like to cut my abs more. I think my main problem is a higher amount of body fat. I have 10-12% body fat, and It covers up my abs. Its not alot of fat, but enough to keep the definition to come through. So my questions are: a) whats a good routine for building ab strength/definition b) how long do you expect it to take for some good definition to show and c) whats a good diet? (btw, here's some quick numbers: 5'10", 145 pounds, 15 years old, bench: 180, squat: 235, clean & jerk: 140, i work out 3-5 days a week and run 3-5 days a week for about 3 miles)
