[Req] Weekly abs and arm workout routine with weights

Anyway, I’m 23, and my height and weight are 5′7" and 130 pounds. And I need to gain some muscles on my upper abs, lower abs, and sides, and arms.

Because I need to get rid of the skinny body fats and gain muscle. Also for my arm I need to gain some muscle because they kind of look smaller compare to other normal weight people of my age, weight, and size.

As for food and current workout routine (without weights) they are listed below.

For vegetables I eat carrots, and etc. As for fruits I eat mostly bananas and oranges. For any other other food I eat rice with water and a little sugar mostly, or one/two boiled scrabble egg with salt and black pepper, and meat I mostly eat pork,beef and sometimes fish. Sometimes I eat Wai Wai noodle with chili powder and mixed spices, but no oil.

I eat about 1800 calories per day.

As for exercise without weights. I do sit up (200 – 400 per day), crunches (200 – 400 per day),
and run for 20 minutes a day.

I very needed this because I don’t feel the burn or pain on my abs after working out anymore.

Thanks in advance. Any helpful advice will be grateful.
