Be shure you have a good diet. That means no junk food no soft drinks and no lage meals. You should eat small meals several times a day. When I met rich franklin there were times that he couldn't talk because he had to keep his eatting on scedual. Try to avoid food or drinks with shuger fat. Try to eat grilled food insted of fried food. Like mentioned be for genetics may not let you develop abs but with this diet and a good work out you can make them solid.
