Cardio is the way to drop fat to reveal your six pack abs. Weight training and ab crunches will make your muscles bigger and more defined, diet will keep your metabolism fast to burn some calories, but cardio is the best way to simply use up your burn calories.

And here's the easiest way to start doing it on a regular basis...

• Choose Something Convenient -

Swimming and rowing are great exercises. But unless you either love them or live near a pool or body of water, they probably won't fit into your schedule.

Choose something that is so convenient you can't possibly procrastinate it. Running is great for this; all you need are some athletic shoes, shorts, and a T-shirt to start.

If you're pressed for space to run, consider getting a lighter kettlebell. You can do kettlebell swings at home with only a few feet of room.

Whatever it is, make sure it's so easy to get ready for and do that you can find no good reason to not do it.

• Work It Into Your Schedule -

Make time in your schedule for your cardio at the beginning of the week. Have a plan of when you will workout, and clear other stuff away from that time. Religiously.

If other people ask you to go out for drinks/party/elope to Istanbul, just say, "No, I'm running (or whatever) then. How about we go tomorrow to visit the Turks?"

Just so that you don't get many conflicts, try to schedule it in the morning or afternoon on weekdays. Scheduling it Friday evening is just an excuse waiting to happen.

Do it regularly, 2-3 times a week in the beginnings. Just do it.

• Make It Fun -

Need I say more? So many people view exercise with the same enthusiasm and guilt as explaining to your professor why you haven't turned in that thesis proposal quite yet.

Whatever you're doing, make it fun. Listen to epic music while you workout, brag about it to your friends afterward, exercise doing something you enjoy, etc.

If you don't have fun doing this, you'll never stick with it to see your abs.

• Sore or Tired? -

You're doing cardio to reveal your six pack, which means that getting horrendously sore isn't top priority. You'll probably be sore when you first start working out, but begin sore is no your goal.

Burning calories, and thus loosing fat, is. So when you're running, if you don't feel sore doing several miles that's good. Increase you running, but keep in mind you want to be able to run regularly to keep burning off the fat, and no just be hobbling to your car.

• Start Just For Three Short Weeks -

Running for a great while can sound intimidating. But doing cardio for just three weeks sounds doable.

Focus on just running for three weeks, and then see how you like it. Is it working? Has your body-fat percentage dropped? Are you enjoying it, or is it more akin to a forced march?

If you're dead set on doing whatever it takes to get six pack abs, this will help you get started on the cardio side of things. But there are other key aspects you need to address in-order to make sure you get that six pack.
