Sounds good.
While you follow this workout plan, you will need to choose smart food choices. Get ALL of your vitamins and minerals, eats lots of proteins and complex carbohydrates. You should gain weight and grow bigger (muscular wise). Good luck buddy!!
When you work out, you want to do sets of muscles. Then you want to wait a week before you go back to them so they can properly repair. This is my workout routine.

To get nice abs you need to lose the fat in the front of your stomach. Only way to do it is cardio. Swiming is the best cardio because you work your whole body with low stress. You lose fat all around your body making you appear more ripped.
