The Best Ab Workout For Six Pack Abs (Based On Science)

In this article, find out the best science-based six pack abs workout you need to do for an impressive-looking midsection.

Let’s face it, acquiring a sculpted set of six-pack abs is a goal that most of us want to achieve.

Most of us also know that in order to achieve this, we need to strip off the excess fat that’s covering our abs by focusing on our diet.

And you’ll have to do this until you get down, depending on your gender:

  • For men – To at least around 10-12% body fat
  • For women – To around 14-18% body fat

That said, achieving well-developed abs and an impressive looking midsection goes beyond this. Now, it’s true that your diet will be mainly responsible for revealing your abs in the first place. But here’s the crucial part. Your training will then be responsible for how developed and how well your abs and overall midsection look once they’re finally revealed.

Meaning that adding direct abs and core work into your routine is definitely needed if you’d like to improve their development.

Basic Anatomy Of The Core Muscles

But in order to best do this, you need to first understand the basic anatomy of the core muscles. That’s because they each play a vital role in contributing to the overall look of your midsection.

First off, there’s the rectus abdominis.

Rectus abdominusWhich is the muscle group most associated with the coveted “six pack”. Now the rectus abdominis can be further divided into two regions:

  1. The upper abs
  2. The lower abs

And research has shown that each of these two regions can be selectively activated given that they’re innervated by different nerves. Which as you’ll see, will be accounted for when we get to our workout.

Upper and lower abs activation

Next, there are the obliques. These run down the sides of the abs. In addition to adding definition to your mid-section, obliques can also help visually taper and narrow your waistline.

Lastly, there’s the serratus anterior situated right on top of the ribs. Which again adds more definition to your midsection. As well as plays a vital role in your shoulder health and injury prevention.

So, as you can see, each of these muscles plays a significant role in sculpting out an impressive midsection. Meaning that your abs routine needs to be designed in a way that hits each of these various muscles.

But this is something that most people fail to do with their ab workouts. That’s really because of the overwhelming number of core exercises out there. Which makes it difficult to pinpoint exactly which ones you should be focusing your time and effort on. And which ones will speed up your core development most effectively.

In this article though, that’s exactly what I’ll show you how to do by crafting the best six pack abs workout for you based on:

  1. Scientific research and
  2. Our anatomical understanding of the core muscles

Exercise 1: Reverse Crunch (Lower Abs)

So the first exercise we’re going to perform is the reverse crunch. Now, the reverse crunch is categorized as a “bottom-up” abs exercise since the hips are brought up towards your shoulders. As a result, it effectively favours the lower abs over the upper abs in terms of activation.

Now the reason for starting out with this movement first in the workout is simply because bottom-up abs exercises are typically the most taxing to perform when compared to other abs exercises. And given that the lower abs are the region of the abdominals that most people struggle with not only losing fat from but also with developing, we’ll want to prioritize them by working them first in the workout when we’re fresh.

However, as I’ve stated in past articles, the key to this exercise’s effectiveness completely depends on how you perform it. Illustrating this is an EMG analysis. It found that subjects who performed the reverse crunch with the commonly done incorrect form where the legs were simply swung up and down were unable to elicit much lower abs activation. Whereas subjects who performed the reverse crunch with the correct form I’m about to show you were able to elicit significantly greater lower abs activation.

How To Perform The Reverse Crunch Correctly

So instead of doing this, what you want to do is:

  • Before you even start, initiate something called posterior pelvic tilt. You can do so by squeezing your glutes and contracting your abs. This will force your pelvis to tilt upwards. And your back will flatten onto the bench. This will pre-activate your lower abs and will help keep them activated during each rep.

Target lower abs proper form

  • Then, when you perform a rep, all I want you to think about is curling your pelvis up towards your belly button. And think about contracting your lower abs. You should feel a very strong contraction in the lower abs as a result of this.

Incorporating The Reverse Crunch In A Six Pack Abs Workout

I’d recommend building up this movement to roughly 2-3 sets of 15-20 reps done with bodyweight and full control. And then move onto performing them weighted and/or with a decline implemented like so for 2-3 sets of 10-15 reps.

This is crucial that you do. Since just like any other muscle like your biceps, for example, you want to overload your abs with more weight over time. This allows you to best develop and stimulate their growth.

Exercise 2: High To Low Cable Woodchoppers (Side Abs)

Next, we’ll move onto a rotational movement: the high to low woodchoppers. This allows us to shift our focus onto the all-important obliques. These are a great option to include in your core workout since they enable us to apply a weighted resistance directly in line with the diagonal way that the oblique fibres run.

And for these, you want to avoid simply swinging the weight down with your arms.

Instead:

  1. Keep your arms extended and elbows locked
  2. Then, use the one side of your obliques to rotate your torso down and across your body towards the opposite knee

I’d recommend a set and rep range of roughly 2-3 sets of 10-15 reps, and adding more weight as this becomes easier.

Bicycle Crunches Are Good Alternatives To Include In Your Six Pack Abs Workout

However, if you find difficulty with this movement then a viable alternative are bicycle crunches.

Woodchoppers exercise alternative bicycle crunchesThat’s because bicycle crunches have been shown by the American Council of Exercise to elicit quite a high activation of the obliques when compared to other common obliques exercises.

Exercise 3: Weighted Crunches (Upper Abs) 

Next, it’s time to move onto weighted crunches. This exercise is a top-down abs movement that we know will now enable us to selectively emphasize the upper abs over the lower abs, which we’ve already worked earlier.

Now there are a variety of weighted crunches you can do here such as the stability ball crunch or weighted cable crunch, which are both effective at targeting the upper abs.

Top down exercise optionsBut the key is that you’re emphasizing the top-down aspect of these movements by focusing on simply bringing the rib cage forward and down towards the pelvis.

Your hips should simply remain stationary as you perform each rep which will enable your abs to be taken through their full range of motion.

And for these, you’ll want to use a moderate rep range of 2-3 sets of 10-15 reps and again, gradually overload these with more weight as your abs develop and strengthen over time.

Exercise 4: Serratus Jabs

The last exercise of this abs workout will be something called serratus jabs. Which we know based on EMG analyses elicits very high activity of the serratus anterior since it effectively applies both of its main movement functions:

  1. Protraction and
  2. Upward rotation of the scapula

Serratus anterior

How To Perform Serratus Jabs

You can use a band or cable and set it up such that your arm travels upward during the jab. Then you want to simply perform an upward punching motion. And reach as far as you can at the end position to protract that scapula and fully activate the serratus anterior.

And we’ll again use a rep range of 10-15 reps per side for these and overload it overtime by increasing the resistance.

So to wrap this workout up for you, here’s how you’d want to construct it.

The Best Six Pack Abs Workout

Exercise 1:

Reverse Crunches: 2-3 sets of 15-20 reps (bodyweight)

BUILD UP TO:

2-3 sets of 10-15 reps (weighted/decline)

Exercise 2:

High To Low Cable Woodchoppers: 2-3 sets of 10-15 reps per side

OR

Bicycle Crunches: 2-3 sets to failure (bodyweight)

Exercise 3:

Weighted Crunches: 2-3 sets of 10-15 reps

Exercise 4:

Serratus Jabs: 2-3 sets of 10-15 reps

I’d recommend performing this workout 1-3 times per week, which can either quickly be done after your main workouts or on your rest days.
