To begin with, I would like to mention that, for many people, getting 6-pack abs isn't an easy process.
It needs serious commitment, but it can be done.
If you are blessed with naturally low body fat and great muscle definition, appreciate it.
Or else, below is a basic 2-step guide which, if followed carefully for a few months, will produce results.

• Healthy eating plan: By all means, this is actually the single most important thing to the bigger picture.
  You could have the most amazing set of ab muscles, but if they are covered with a coating of extra fat, you will not see them.
  Break up your day with five or six mini-meals simply because this will jump start your metabolic rate.
  And also stop consuming the food that is preventing outcomes: white bread, loads of pasta, soda pop, snack, junk food, hydrogenated oils, sugars and fructose corn syrup.
  As an alternative, replace them with foods that will let you achieve your ultimate goal: Oatmeal, olive oil, whole grain breads, fruits, veggies, nuts, peanut butter, chicken, fish, protein and water.
  However, be realistic else you may miss the point.
  Make a conscious effort to drastically improve your eating routine because obtaining a six pack will be unachievable if you do not.
  
• Workout: You should concern yourself with 3 diverse workouts: cardio, weight-lifting and ab workouts.
  And aim to exercise no less than 4 times weekly.
  The cardio exercise you need to do can be anything: walking, running,jogging,swimming, cycling, and what have you, whichever cardio will work for you, and ensure that you will stick to it.
  At least for 30 to 45 minutes minimum, twice a week.
  Weight training is very important simply because three pounds of extra muscle burns as many calories as a 1 mile running, and this is when you're just resting around.
  Target 30-45 minutes minimum, twice a week.
  The final exercise you have to include into your exercise routine is ab workouts.
  Try and work your ab muscles no less than three times weekly.
  There are actually a ton of diverse abs workouts you can do, so try to find 3 or so you enjoy doing so that you could mix up.
  Certainly, that's it.
  Stick to the above for three months on a serious note, and while outcomes will vary from individual to individual, you will experience some improvement.
  It will take sincere commitment on your part, but think of the experience you will get when you look in the mirror and like what you see.
