Do Abs Workouts Affect Height Growth?


 

Abs workouts actually help you grow taller.

 

But not  directly .

Once I understood how the spine actually works, core training became a regular part of my routine and it should be part of yours too.

Your abs aren’t there just for aesthetics.

They support your spine from the front.

A spine that’s properly braced sits taller, stays decompressed, and doesn’t collapse under daily gravity the way a weak, unsupported one does.

Let me walk you through why that is  and the five exercises I recommend to fix it.

 

First, your abdominal wall is made up of both superficial and deep abdominal muscles on the façade as well as muscles in the back and together they help keep your body stable, balanced, and protect your spine.

 

The 4 Main Abdominal Muscles

RECTUS ABDOMINIS

 

The “six pack” running down the front of your stomach.

 

Keeps your torso stable whenever you raise up from a reclined position.

EXTERNAL OBLIQUE

 

The superficial muscle on both sides of the abdominal wall that traverses from just below the rib cage to the front of the abdominal wall just above the pelvis.

Internal oblique muscles

 

Located below the external oblique muscles and slightly on top of the transversus bdominis.

 

Strengthening this muscle is very vital for preventing lumbar spine compression and improved back health since the internal obliques are attached to the lower back muscles that run up to the thoracic or chest area (The erector spinae fascia).

 

Hence, strengthening the internal obliques strengthens the erector spinae fascia making it more able to resist any forces that may lead to lumbar spine compression like gravity or any force that results from carrying heavy loads on your head or back..

The transverse abdominis

 

Located very deep beneath the rest of the abdominal muscles.

 

It keeps the hip joint and lumbar spine in position and helps us to forcefully exhale air from the lungs when performing activities that necessitate control of breathing like singing.

 

How Weak Abdominal muscles can affect your height.

 

When the abdominal muscles are weak, the spine is not properly supported which leads to changes in body alignment or slouching.

 

This is because it’s the back muscles especially those that run from the lower back to thoracic region ( the erector spinae and multifidus muscles) that play the vital role of keeping the spine in position and withstand any forces that may lead to spinal compression like gravity thereby keeping the spine in an erect position, preventing slouching and lower back pain .

 

There’s a second issue too.

 

Weak abdominal muscles allow excess pressure to build up around the lumbar spine — the lower portion of your back.

 

That compression affects the discs between your vertebrae.

 

Compressed discs mean less spinal height.

 

Less spinal height means, well… you know.

Slouching will definitely make you appear a couple of inches shorter. [1]

3. Strong abdominal muscles will also effectively carry the weight of your body and bones, thus taking some of the unnecessary pressure off your spine.

It’s therefore imperative to include abdominal exercises in your  grow taller exercise plan.

 

The Most Effective abdominal workouts

 

The effective abdominal exercises listed below target at least one of the four main abdominal muscles and all of them can be performed at home.

 
1

The Bridge/THE PLANK

The plank is probably the most recommended core exercise for a simple reason: it trains your abs the way they’re actually designed to work. Most abdominal exercises involve movement.

 

The plank doesn’t.

 

You hold a static position, and your core muscles do exactly what they do in real life — stay firm under load.

How to Do It :
 
Get into a prone position on the floor.
 
Support yourself on your forearms and toes, keeping your body in a straight line from head to heel.
 
Tighten your core and squeeze your glutes to stop your hips from dropping or rising.
 
Hold for 30–60 seconds. If you’re just starting out, 10–15 seconds is fine. Rest a few seconds, then repeat. Aim for at least 3 sets.

Why the plank is effective

 

The plank is effective because it engages not only your core but also shoulder, back and hip muscles but most importantly, fitness experts prefer the plank for core strengthening because while performing the plank exercise, the abdominal muscles are trained to do exactly what they are meant to do;

 

That is remain static or in position which helps to make them even stronger.

 

Muscles targeted: erector spinae, external obliques, rectus abdominis, transverse abdominis.

 
2

Side plank

The side plank is a little complicated due to the fact that to execute this exercise appropriately, the entire body weight has to be supported on two contact points that is the elbow and outside of your foot..

 
How to Do It :
 

Simply support your body on your elbow and legs diagonally to the floor while maintaining a leveled position and placing the free hand on your hips.

 
Hold on to this body position for 15 to 60 seconds or even longer depending on your fitness level before switching to the other side.

Why it is effective

 

While performing this workout, a number of muscles are targeted most importantly, the external oblique muscles .

 

Muscles targeted: external obliques, chest, thighs, shoulders, hip adductors.

 

Such muscles are rarely kept active thus with the side plunk, it’s an opportunity to activate them.

 
3

Push ups

One of the most common fitness excises though not as easy to execute as it may seem.

 

Push-ups are usually thought of as a chest and arm exercise. But when done correctly, they’re also a solid core exercise.

 

The key word there is “correctly.”

 

The most common mistake is letting your hips sag or rise during the movement,  which kills the core activation entirely…

 
How to Do It :
 
Begin by supporting your body on your hands and toes making sure the hands are positioned approximately shoulder-width apart.
 
Make sure that the body is perfectly aligned from the back to your legs and the abdominal muscles are tight.
 
Tightening your abdominal muscles prevents the hip – to the back arc area from falling in and increases the effectiveness of the push ups in strengthening the core muscles.
 

3. The next step is to lower your body towards the floor until  the part of the arm between the elbow and shoulder joints is at approximately a 45 degree angle to your shoulder.

 

4. Complete the push up exercise by ascending the entire body to the starting position.

Perform as many push ups as you can depending on your fitness levels. The more the better though 10 – 20 for most people is enough.


Push-ups


why push ups are effective

 

whenever you perform the push up exercise, the transverse abdominis and rectus abdominis muscles are engaged .

 

Most strength training instructors put a lot of emphasis on the rectus abdominis muscles because they are the center of your core strength.

 

They are the muscles that keep your body straight and support your entire body to prevent it from slouching.

 

Muscles targeted:   shoulder joint muscles, transverse abdominis, rectus abdominis, chest muscles, fore arm muscles,  back muscles, as well as biceps and triceps.

 

Push ups are simply the ultimate upper body workout exercise.

 
4

Bicycle abdominal exercise

The bicycle abdominal exercise is quite complex in the beginning especially if you are over weight but once you get used, it’s relatively easy to execute and very effective in strengthening your core muscles.

 
How to Do It :
 
Lie on the floor in a reclined position and place your arms behind your head, gently assisting it with your fingers.
 

2. Raise both your knees towards the abdominal area and mimic the cycling motion as if you are cycling in the air.

 

3. As you execute this motion, ensure that the neck is completely off the floor by supporting the back of your head with your hands.

 

Move the right elbow towards the left knee while stretching out the right leg.

 

And do the same with the left elbow and right leg as you stretch out the left leg.

Why it is effective

 

The bicycle exercise is very effective in strengthening and toning mainly the rectus abdominis muscles .

 

With this exercise, you also strengthen the muscles around the hips since these muscles keep contracting as you cycle in the air.

5. Sit ups

Sit ups are a very effective workout to strengthen your core muscles that’s why they are favored by many fitness instructors not only in gyms but also during training sessions in sports and the military.

 

They are relatively hard to execute especially if you are performing them for the first time.

 
How to Do It :
 

Begin by lying on the floor in a supine position.

 

Bend your knees and place your hands behind the head.

 

Elevate your torso from the floor as you move your head towards your knees.

 

For starters, you may require someone to sit on your feet or you may place some weight on your feet to prevent the legs from moving as you elevate the torso from the floor.

 

Wind up the sit up exercise by resuming the starting position or reclining your head back to the starting position with the hands placed behind the head.

 

Ensure that your head doesn’t touch the floor.

 

Just like the push ups, you can do as many sit ups as you wish though for starters, aiming for 5 – 10 will be a good starting point before aiming for more as your fitness levels improve.

 


Sit -ups abdominal exercise


Why Sit ups are effective

 

Sit ups target a wide range of abdominal exercises unlike other abdominal crunches.

 

Muscles targeted:  The rectus abdominis , the external and internal oblique muscles,  as well as the muscles along the hip joints.

 

A FEW THINNGS TO KEEP IN MIND

 

1

Several studies have demonstrated that even if you perform many abdominal workouts or crunches, it has no effect on reducing the waist line size or abdominal fat as well as the entire body fat.

 

If you are struggling to eliminate belly fat, you can visit how to   get rid of stomach fat page    for the causes of stomach fat accumulation and how to get rid of it fast.

 

2
 

After analyzing the electrical activity produced by abdominal muscles in different positions, it was ascertained that the rectus abdominis or ‘six pack’ muscles and the external oblique muscles are almost entirely inactive when you are walking or in a standing position unless if you are carrying a load on your head or back.

 

So, walking almost has no effect on your rectus abdominis and external oblique muscles.

 

However, your internal oblique muscles are activated when you are in an erect position, sitting or walking because they play an important role of stabilizing the pelvis.

 

On the other hand, the rectus abdominis and external oblique muscles become active when you assume a supine or reclined position.

 

3
 

Workout your abdominal muscles at least 3-5 times in week or even everyday if possible and include at least two or three or even more different core excises to counter lumbar spine compression and it’s effects including lower back pain.

 

Studies demonstrate that core stabilization exercises whether used alone or in conjunction with other treatments can significantly ease lower back pain as well as pain around the pelvic girdle or the hip joint and prevent pain from recurring.[2]
