We all want to have a body defined by exercise, but very few people know that 35% of the definition is thanks to eating habits. It is necessary to eat many proteins and natural carbohydrates, stop eating high-fat and fried foods, also sleep 7 hours and eat green vegetables along with many fruits.
Since you want to get a six pack as fast as possible, you must keep your mind motivated, remember that without great effort you will not see results, I recommend doing daily abdominal exercises with variable movements. You can start with classic crunches by twisting the chest, you can also lift the legs and alternate the movements to the sides. You can try to place the elbows and hands on the ground, holding them with the tips of the feet and keeping the abdomen parallel to the floor for 2 minutes.
