How to know what exercises should i do to get my abs ripped?

2 things: The two things to do are: 1. Train the abs to get them in shape - crunches, other core exercises 2. Strip away the fat covering the abs - by reducing caloric intake and regular aerobic training - interval running, biking, insanity workout, whatever works for you to reduce overall body fat to show off your abs - with too much fat, you can't see the detail of the ripped abs.
