This abs workout will build off of our previous discussion on The Best Abdominal Exercises for Flat Abs. This post will focus on more advanced abdominal training for those people who have reached their flat abs goals and are looking for a rippling six pack. If you’re still striving to reduce belly fat then start with the previous post before applying what follows.

So let’s assume your abs have flattened a bit and the love handles are shrinking, but you have yet to bring out definition or tone. For most people the combination of interval and resistance training with a proper diet is more than enough to shred the abs. But there are a few of us that for whatever reason plateau once we near that elusive goal. So our workout plans need to adapt just as our bodies have in order to hit our abs with more intensity.

Let’s look quickly at the body of a sprinter versus the body of a marathon runner. Until recently (cross training is much more prominent these days) marathon runners tended to be slender, carry little muscle, and lack the detailed muscle tone we see in sprinters. And this had everything to do with the type of training. Sprinting requires and develops fast twitch muscle fibers, whereas jogging develops primarily slow twitch. This results in muscular hypertrophy in sprinters which builds their bodies and shows greater definition. This is what we are looking for.

Marathon runners by comparison, despite the fact that they run for hours on end and have lean midsections, rarely show the rippling six packs of sprinters. There are two reasons for this. The first, as I’ve just said is due to the fact that sprinting is a sport requiring fast twitch muscle fiber development resulting in larger muscles. The second reason is that sprinting stresses our nervous systems and muscles to a much larger degree, forcing the release of human growth hormone and other powerful fat burning and muscle building hormones. Jogging for long periods of time on the other hand can cause our bodies to release cortisol, a stress hormone which tells our bodies to store fat.

So if you’ve reached the point of flat abs, jogging and long cardio sessions may actually be detrimental to your progress. It’s important to recognize this peculiar hormonal response and utilize contrary training techniques in our ab workouts. We’ll need to stick to short and intense training sessions rather than longer cardio sessions, and we’ll need to concentrate a little more on exercises which stress our cores.

In my own training I reduce my abs workout (assuming, like I’ve said I’ve already reduced my belly fat and have just to bring out definition) to short intense abdominal exercises followed by short and intense interval training or sprinting. The abs exercises pre-exhaust my core before I sprint, and then running forces my core into overdrive to keep me stable while running. It also works supporting muscles that are hard to reach with normal abdominal exercises.

My preferred exercises at this level of training are those which draw more power from the lower abs through lifting the legs rather than those which concentrate on the upper abs through crunches. I do reclining leg raises on a decline bench or hanging (from pull-up bar) leg raises, for 3 to 4 sets of 10. You will not normally feel like you’ve exhausted your abs because these kinds of exercises rarely generate lactic acid to the same degree as a set of 20 crunches, but lactic acid is not an indication of muscular stimulation.

You’ll notice your work as soon as you step on the treadmill for your sprint session, and then days letter once your midsection has firmed. Once on the treadmill, warm up for 5 minutes with a moderate jog, and then either transition into the interval training I’ve outlined in Why Interval Training Needs to be a Part of Your Flat Abs Workout Plans or simply resolve yourself to 3 to 5 one minute sprints. By the end of the minute you should be close to failure, and you can rest 2 to 3 minutes between sprints by walking at a decent pace.

If added to your flat abs workout plans this abs workout done once or twice a week will turn your flat abs into rippling ones. It’s important to remember however that too much exercise is just as bad as too little. Your abs need time to recover and grow stronger, and any abs workout that is done intensely, should be done infrequently, once or twice a week max. A less intense abs workout can be performed three or four days a week, but in my opinion is less effective.
