Train this Muscle FIRST.

Neck Hump Diaphragm Muscle example of what it looks like and placement

Why Train The Diaphragm First?

neck hump, chronic shoulder, neck, upper & lower back aches, joint pains, incontinence, and ED are all signs the diaphragm muscle needs strengthening.

As with everything on The Simple Self Care Lifestyle, knowing HOW the body is set up to work means we can use the knowledge to leverage and layer our Micro Decisions to get results.

We will get long-lasting Neck Hump relief when we FIRST strengthen the diaphragm. This is because the diaphragm muscle is the spine’s number 1 stabilizer.

After we strengthen the diaphragm, every other muscle group that we use to layer on exercises for the Neck Hump will be easier for us to do, more efficient, and way more effective, plus results for all of them will be exponential.

Fixing a Neck Hump Has Exponential Benefits!

Unwinding a neck hump is a big player when it comes to achieving our 1 GOAL of Optimizing Our Body. Training our diaphragm FIRST gives us an advantage when it comes to fixing a Neck Hump!

Muscle Skeletal Imbalance

A Neck Hump is an indication that the Muscle – Skeletal System is out of balance.

Core Concept 1 all Our Body Systems are interconnected and DEPENDENT on each other means this imbalance is impacting our body system-wide.

This is Important

โ˜ผ When the Muscle-Skeletal System is out of balance, as with a neck hump, it impacts all our other body systems.

There is much more to gain by unwinding a neck hump than what meets the eye.

Exercises Do Work for a Neck Hump IF

The neck region of the Spine, where the hump is, is better able to reposition and stay repositioned with the right exercises IF

Let’s look at the Diaphragm muscle and how to train it.

Neck Hump Diaphragm's role

Number 1 Spine Stabilizing Muscle

The diaphragm is well-known as a respiratory muscle, but it is also the NUMBER 1 Spine Stabilizer!

Over time, as the diaphragm weakens, it stresses other parts of the spinedestabilizing it and causing achespains, and skeletal muscle adaptations like a Neck Hump.

As our diaphragm gets weaker, our breathing becomes shallower.

Shallower breathing promotes multiple physiological cascades in our body like:

  • anxietylower mood
  • increased stress hormones, and 
  • weakening pelvic floor muscles, to name just a few.

All of which can be contributing factors to poor posture. 

We have less oxygen, we feel more tired, and smaller and smaller inconveniences feel like major stressors.

Our body senses an increased stress level; muscles begin to chronically contract and then stay contracted longer and longer.

Over time chronically tight muscles create postural adaptations and inflammation that lead to a change of posture.

The altered posture from a weaker diaphragm slowly creates chronic aches, pains, and a more prominent neck hump.

Neck Hump. Aches Pains due to a Weak Diaphragm

Fixing a Neck Hump: The only way postural exercises will bring long-lasting results so we can unwind our neck hump is to start with strengthening our diaphragm muscle FIRST.

The Diaphragm Muscle

Neck Hump dependent on the diaphragm

Above is the amazing diaphragm muscle and its location.

โ€œIt is concluded that the diaphragm consists of two muscles that act differently on the rib cageโ€ (1)(italics added)

It is concluded that the diaphragm consists of two muscles that act differently on the rib cage

The Diaphragm Sits under your lungs.

Neck Hump relationship to Diaphragm Muscle placement and Action
  • The Diaphragm sits under your Lungs
  • Attaches to the front of your ribcage
  • As well as the sides of your two bottom ribs
  • The illustration below shows that it also attaches to three of your lower spine vertebrae via a central tendon.

Neck Hump, Aches & Pains From A Weak Diaphragm

Seeing how the diaphragm is positioned sometimes helps make it easier to envision how aches and pains can arise in our upper, middle, and low back regions.

Neck Hump aches and Pains

Training the Diaphragm Muscle Can Help Aches & Pains All Up & Down the Spine.

Many people experience aches and pains in the neck and lumbar areas of the spine.

Research concludes that training the diaphragm muscle results in the relief of most spine discomforts. (2)(3)(4)(bold added) AND SO MUCH MORE like- Helping to Fix a Neck Hump!

The Diaphragm Muscle isnโ€™t just for Breathing. It Impacts Our Posture Too!

The functions of the diaphragm do not stop locally in its anatomy but affect the whole body system.

(5)(italics and underline added)
Neck Hump and pains up and down the spine

We are mostly aware of the diaphragmโ€™s job as a prime respiratory system regulator.

This respiratory muscle is on auto- we do not need to think about it for it to work. It continually contracts. This enables us to breathe in a stable, rhythmic way. It does KEY off our nervous system. Here is how our neck hump gets entangled.

The rhythm keys off our nervous system.

Neck Hump unwinds as you train your diaphragm

Why Is All This Important to a Neck Hump?

Our Diaphragm influences our nervous system. AND our Nervous system influences our diaphragm. Both are connected to our posture.

How can that be?

Core Concept 1 again. Our Body is made up of Systems. The Systems are all interconnected and DEPENDENT on each other. If this is your first visit there is 1 Goal, 1 FOCUS and Micro Decisions that are the foundation of everything on The Simple Self Care Lifestyle! Being aware of the 1 Goal, 1 FOCUS and Micro Decisions add up to achieving the results we want. Including fixing Neck Humps.

Quick Re-Cap & On to The Muscles

Our nervous system influences our diaphragm and vice versa.

When we strengthen our diaphragm, we calm our nervous system.

When our nervous system is calm, we improve how multiple body systems function, including our muscle-skeletal balance.

strong diaphragm (or weak one) influences the nerve that runs from our brain all the way down our spine (shown below).

Neck Hump and the Vagus Nerve and HPA Axis to illustrate how scent can influence the self care of the entire body

strong diaphragm has a calming effect on this nerve. This calming effect is beneficial to all the organs that make up our systems; that create our body. Including our muscle-skeletal system.

Reduced Muscle Tension Helps Set The Stage For Results

When our Muscle Skeletal System is informed by our Nervous System that the world is okay, the excess muscle tension in the big and small muscles that act on the spine reduces.

Once muscles reduce their tension, they can move into and stay in a relaxed posture more easily.

This helps set the stage for the spinal exercises we layer on next to effectively rebalance the multiple layers of muscles that are responsible for our neck’s position.

dowagers hump. Arrows pointing to the little spinal muscles

A few everyday instances of the bodily functions that improve when the diaphragm is strengthened and the muscles have the opportunity to rebalance include but are not limited to:

  • improved posture (unwinding of a neck hump)
  • decreased joint pain
  • eliminating tingling and numbness in shoulders, arms, and hands from compression
  • frequency and urge to urinate diminish
  • bowel movements improve
  • lymphatic movement is more effective
  • ED
  • ability to lift heavy objects safely
  • asthma, COPD improve
  • mood improves
  • anxiety decreases
  • sleep is sounder
  • focus is easier
  • endurance increases
  • lower blood pressure
  • heart rate optimized
  • stronger lungs
  • delivering a baby is muscularly easierโ€ฆ

The improvements are a result of your Nervous Systemโ€™s benefit that it receives from deeper respiration.

Neck Hump and the diaphragm muscle loop

โ€œTo have a strong diaphragm, you must breathe deeply.

To breathe deeply, you must have a strong diaphragm.โ€

stronger diaphragm is the result of deeper respiration. An excellent place to start improving your breathing is a technique called 4-7-8 breathing or measured breathing. Other popular deep breathing techniques you may have heard of are:

  • Box breathing,
  • Resonant, or Coherent breathing.

It only takes a minute for the Nervous System to receive the positive feedback from Deep Breathing.

The biggest hurdle for most is believing something so simple can have such huge impact. I was one of those. It took me close to a decade to fully understand the power and the impact it has on every facet of our life- including our Neck Humps. To help bolster your confidence, below is a video that might be helpful.

Navy Seals use it in training for the impact deep; slow breathing can have on calming the nervous system in high-stress situations. The spot in the video referring to Navy Seals using Measured breathing is 07:14

Now, Let’s Practice.

Iโ€™ve created two pictures.

1. of how we typically use the diaphragm when we Exhale during exercise (or when we lift objects).

2. how we want to use our diaphragm to strengthen it.

HOW to Train the Diaphragm Muscle FIRST

At 02:19 I walk through how we typically use our diaphragm and how we want to use it. Plus we practice finding the muscle that helps us strengthen our diaphragm…

We Typically Do This.

When we exert effort and exhale deeply, we tend to pitch our upper body slightly forward.

Avoid this type of Exhale

TYPICALLY We:

Contract most of our upper and middle stomach muscles, pushing the air out.

The sound of the air coming out is more of a blowing.

The arrows show that we create a downward pressure inside the abdomen when we exhale this way.

This downward pressure pushes on the pelvic floor muscles.

The more the pelvic floor muscles are pressed downward, the more the abdominal cavity loses spine stability.

A weak diaphragm and pelvic floor muscles contribute to a posture promoting a neck hump.

Below is how we want to EXHALE while exercising or exerting effort to Train our Diaphragm Muscle.

Optimally,ย We Would Like Toย Do This

Exhale Desired for Spine Stability

Exhale instructions:

Maintain an upright upper body posture.

Whether standing, sitting, or lying down, we want to use the lower third of our abdomen to PRESS the air in our abdominal cavity up and out through our open mouth.

The lower third of your AB muscles is the section from below your belly button down to your pelvic bone.

When you use the lower third of your abdominal muscles to exhale completely, your pelvic floor muscles will rise because they are meant to work together with your diaphragm.

The stronger the diaphragm, the more completely your lungs will empty. This is good for you in many ways. Iโ€™ll create a post on that later.

The sound of the air coming out of your open mouth is a huhhhhing sound.

When we exhale using the lower third of our abs:

  • during exercise
  • lifting something heavy
  • even getting up and down from a chair

we are strengthening the diaphragm and the pelvic floor.

The strengthened diaphragm and pelvic floor provide spinal support.

stable spine promotes good posture.

Good posture opens up the possibility of correcting a neck hump.

Letโ€™s Find The Lower Third of Your ABS

The technique Iโ€™ve found the most useful in helping clients find the lower third of their abdomen is to imagine youโ€™re trying to blow up a balloon.

Finding the muscles to help train the diaphragm woman blowing up balloon as exercise to find the lower 1/3 of her ab muscles

If you were blowing up a balloon, you probably can imagine youโ€™d press the lower 1/3 of your abs to make the balloon go up.

We typically use our lower abs when blowing a balloon because we really wonโ€™t get far if we are just blowing some air from our lungs.

As you blow up a balloon, you typically inhale through your nose so you do not lose the air already in the balloon.

Then as we attempt to get more air into the balloon, we push from our lower belly.

That is the region of the muscle to use with each exhale. It is the lower 1/3 of your ABS.

When you press the air UPWARD in your abdominal cavity ( see E for E post to see how it all works)

The air presses on your diaphragm, which helps place upward pressure on your lungs.

This technique will train your diaphragm.

  • Inhale through the nose.
  • Mouth relaxed and slightly open so the air can come out.
  • Press the Lower 1/3 of your ABs slowly and completely so the air in your abdominal cavity presses up and out of your open mouth.

Thatโ€™s it! Simple but often not easy until you practice. Repeat, repeat, repeat.

If you havenโ€™t blown up a balloon, think about how you would blow out a candle far away or blow a bubble using a bubble wand that is positioned farther away from you.

Each of these can help find the lower third of your ab.

Once youโ€™ve found your lower ab muscle, practice it a few times right before beginning any exercise.

Over time this spine-stabilizing exhale action will become second nature

In the meantime, there are ample times throughout our day when we can strengthen our diaphragm by taking advantage of this exhale technique:

  • when you pick up a child
  • carry a laundry basket
  • lifting groceries in and out of the cart or car
  • getting in and out of the car yourself
  • vacuuming
  • moving from a seated to a standing position
  • exercises
  • standing up from a squatted position
  • any time you lift something

Each time by simply using the lower third of your abs to press the air up and out, you will be strengthening your diaphragm.

The stronger your diaphragm, the better your posture.

The better your posture, the easier it is to use Focus 2 and 3 to Fix your Neck HUMP!

…studies concluded the effects of deep abdominal muscle strengthening exercises on respiratory function and lumbar stability. The finding is that core stabilization starts with the proper function and activation of the diaphragm.

The diaphragmโ€ฆplays a role in respiration and trunk stability by controlling intra-abdominal pressure and reducing the stress on the spine through cooperative action with the abdomen and the pelvic floor muscles.
