What do you need to buy to get abs?   Nothing, Abs are FREE!!!!!  Everybody has abs, but you can't see them until you lower your bodyfat.   High bodyfat is not just for people who are overweight, you can be skinny (skinny fat) or  even underweight and have high bodyfat so that means no abs for you until you make some changes in your eating.  There are plenty of skinny little size 2 girls who have belly rolls because they are making bad eating choices.  For the skinny girls, losing weight is not the answer,... the answer is to change your eating and stop eating so much crap.

You don't need any potions, powders, magical miracle pills, or crazy contraptions that give you abs in 7 seconds.  There are no magical methods that exist.  So if you are looking for magic, keep on looking and good luck to you.

Workout consistently and eat right.  And don't eat any junk food.  That is how you will get abs and it takes time and dedication.

You get visible abs by having low bodyfat.  You can do 5000 crunches a day and you'll never in your life see your abs unless you lower your bodyfat.  That means you can't eat all the delicious treats you love if you want to have abs. If I were eating peanut butter cheesecake everyday, there would be not a single soul coming to this website to find out about getting abs, because you wouldn't see them at all, they would be covered in fat.

I don't make the rules,  I just follow them.  If you think you have the clever idea of just cutting your portions but still eating plenty of crap, you'll at best be a small size but still jiggly all over,   not lean, so no abs for you.     So you can have abs if you are willing to work for them.  Are you?   That is what will determine your success.   If you stop eating junk food for one day it won't make a difference.  You have to commit yourself to working out regularly and eating right.  And yes,... it's hard.
