How to fix Flared Ribs

What are Flared Ribs?

Flared ribs is where the lower portion at the front of your rib cage protrudes forwards and out.

It is associated with an increased arch of the lower back.

Ideally – The rib cage should feed directly into the pelvis.

Causes of Flared Ribs

a) Weak abdominal muscles

The abdominal muscles are responsible for tilting the rib cage downwards and inwards into a more neutral position.

b) Hyperlordosis

flared ribs

Overactive/tight muscles (such as the quadratus lumborum, paraspinal erectors and latissimuss dorsi) can cause an excessive arch in the lower back which results in a rib flare.

Hyperlordosis is associated with an anterior pelvic tilt.

c) Ineffective breathing

The diaphragm is the primary muscle that is responsible for breathing.

Ineffective breathing will result in the recruitment of compensatory muscles to assist with respiration.

As a result, over-activity of these muscles can lead to flared ribs.

d) Lack of true shoulder flexion

When reaching over head –  if you lack true shoulder mobility, your ribs will tend to flare out as a compensation as you tilt your torso backwards.

e) Pectus excavatum

This is a congenital chest wall deformation which involves the ribs/sternum causing a sunken chest appearance.

As this is of genetic origins, we are unfortunately unable to significantly impact this.

 “… Do I have a rib flare?”

You should be able to visibly see if your ribs are flaring outwards.

If in doubt, do this:

test for flared ribs


  • Whilst standing, place both of your hands on your stomach.
    • (slightly below the lower section of the front of your ribs.)
  • Proceed to push and drag your hands up towards your chest.

Results: If you can feel your lower ribs significantly protruding outwards, then it is likely that you have flared ribs!

How to fix Flared Ribs

Note: Please make sure that you perform all of these exercises in a pain-free and gentle manner. 

1. Releases

a) Lower back


  • Place a massage ball underneath the muscles of your lower back.
  • Apply an appropriate amount of body weight on top of the ball.
  • You may perform gentle circular motions to increase the pressure.
  • Aim for 1 minute on each side of the spine.

b) Latissimus dorsi


  • Place the side of your upper body on top of a foam roller. (see above)
  • Apply an appropriate amount of body weight.
  • Proceed to roll up and down.
  • Continue for 1 minute.
  • Repeat on other side.

2. Stretches

a) Lower back

stretches for flared ribs


  • Whilst sitting, lean all the way forward.
  • Aim to feel a stretch in your lower back.
  • Hold for 30 seconds.
  • Repeat 1-3 times.

b) Latissimus dorsi


  • Whilst standing side ways to a door frame, tilt your torso by reaching over with the arm that is furthest away from the wall.
  • Firmly anchor this arm by grabbing onto the side of the door frame.
  • Lean away from the anchored arm.
  • Aim to feel a stretch on the side of the body.
  • Hold for 30 seconds.
  • Repeat 3 times.
  • Do both sides.

3. Breathing and the Core

Before you start any strengthening exercises to fix your flared ribs, it is ESSENTIAL to understand how to:

a) engage your core muscles,

b) breathe properly/efficiently and,

c) maintain optimal alignment.

(… all at the same time!)

Here’s how to do it…

The Core breathing complex:

breathing and flared ribs


  • Assume the position as shown above.
  • Breathe in.
  • As you breathe out,  slowly push out ALL of the air out of your lungs:
    • Engage your core muscles (“draw belly button in AND gently tense your abdominal muscles”)
    • Lower your rib cage
    • Flatten your lower back completely
  • Whilst maintaining this position, breathe in towards your abdominal region.
    • Imagine the whole circumference of your torso/abdominal region inflate.
    • Breathe out: Force the air out of your lungs as you engage your abdominal muscles.
  • Keep your neck and chest completely relaxed.
  • Repeat 10 times. (… or as long as it takes to get it correct!)

** Note This specific contraction MUST be performed throughout all of the following exercises. **

4. Strengthening

I have arranged these strengthening exercises to reduce flared ribs in order of increasing level of difficulty.

You do NOT need to do all of them.

Pick 1-3 exercises that are challenging and progress as appropriate.

a) Dead bug (with arm drop)

Core flared ribs


  • Assume the dead bug position. (see above)
  • Activate the Core Breathing Complex.
  • Lower your arm/s down behind you as far as you can go.
    • Breathe OUT as you do it.
    • Breathe IN as you return to the starting position.
  • Keep your lower back completely flat on the ground.
  • Repeat 10 times.
  • To progress: Hold onto a weight

b) Dead bug (with leg drop)


  • Assume the dead bug position. (see above)
  • Activate the Core Breathing Complex.
  • Lower your leg as far as you can go.
    • Breathe OUT as you do this.
    • Breathe IN as you return to the starting position.
  • Keep your lower back completely flat on the ground.
  • Alternate legs for 10 repetitions each.
  • To progress: Drop both legs together.

c) Shoulder flexion with bar


  • Sit up right on a chair.
  • Activate the Core Breathing Complex.
  • Whilst holding onto a bar, raise the bar over your head.
    • Breathe OUT as you do this.
    • Breathe IN as you bring you arms down.
  • Do NOT let your ribs to flare outwards.
    • “Keep the ribs down”
  • Repeat 10 times.
  • To progress: Increase the speed.

d) Wall angel


  • Stand with your back to a wall.
  • Activate the Core Breathing Complex.
  • Keep your back and arms pulled backwards as to remain in contact with the wall throughout movements.
  • Place your arms in the ‘W’ starting position.
  • Transition to ‘I’ position.
    •  Breathe OUT as you do this.
    • Breathe IN as you return to the “W” starting position.
  • Do NOT let your ribs flare.
    • Keep the lower back flat on the wall.
  • Repeat 10 times.

e) Plank


  • Get into the plank position. (see above)
  • Activate the Core Breathing Complex.
  • Make sure your lower back does NOT sink in.
    • Keep the core engaged.
  • Hold for 30 seconds.
  • Repeat 3 times.

f) Pull downs


  • Whilst standing with a slight forward lean, pull the resistance band downwards.
  •  Activate the Core Breathing Complex
  • Slowly let your arms recoil to the over head position.
    • Breathe OUT as you do this.
  • Your torso should not move during this exercise.
  • Pull the resistance band back to starting position.
    • Breathe IN as you do this.
  • Repeat 10 times.

g) Pull overs

exercise for flared ribs


  • Lie on the floor whilst holding onto a weight in the air.
  • Activate the Core Breathing Complex.
  • Slowly lower the weight as far as you can go.
    • Breathe OUT as you do this.
  • Bring the weight back to the starting position.
    • Breathe IN as you do this.
  • Do not let your ribs flare upwards.
  • Repeat 10 times.

h) Roll outs


  • Grab an exercise ball.
  • Whilst kneeling, place your forearms onto the ball.
  • Activate the Core Breathing Complex.
  • Proceed apply your body weight onto the ball as you roll it as far forward as you can.
    • Breathe OUT as you roll forward.
    • Breathe IN as you return to starting position
  • Repeat 10 times.

5. Improving function

Throughout the day, make sure that you are consciously maintaining your ribs in a neutral position.

Remember – “Keep the ribs down”

As you get better with these exercises, the aim is to get your ribs to NATURALLY adopt this position.

“Mark!… What happens if the rib flare is more on ONE SIDE?”

Great question!

It is actually very common to have a more prominent rib flare on one side.

Without getting into too much detail as to why this occurs, it is essentially related to how your torso is orientated. (… more on this in another post)

Here’s what to do: Focus MORE on keeping the side of the more prominent rib flare DOWN whilst performing the above exercises.


As you correct your flared ribs, you may actually find that your upper body becomes more hunched over.

Wait a minute, Mark… Are you saying that when you fix one problem, another develops?

Yes – Since your current posture is based on you having a rib flare, by correcting it, other parts of the body may go out of alignment.

  1. Hi Mark,
    I believe I have developed rib flare from lack of exercise and core muscle. Now my ribs hurt, and I have lower back pain. Will these exercises help build strength and get my ribs back to the way they were? My doctor doesn’t even know what’s wrong with my ribs, I had to tell him and he still has no answers for me. I’m a 46 year old woman and I feel hopeless and I feel like crying often because of how this makes me feel and look. My body just hurts due to lack of muscle. Can you offer any advice? Or at least let me know that if I start and continue your exercises above, I can return to the way I was and become stronger? Thank you.

    • Hi Christina,

      The exercises mentioned in this blog post will help get those flared ribs into a more neutral position.

      From here – you can start to gradually do more strengthening exercises in a more neutral position.


      • Hey mark I’m 18 year old boy. I noticed that my left rib flared 2 months ago and before 2 weeks I noticed this, I had trouble with my breathing. Thwre is no pain and nothing else but rib flare just suck.I got chest x ray and it says b/l Hilar prominence. what doies that mean. please reply

        • Hi,

          This refers to a lung structure. Unfortunately – this falls outside my realm of knowledge so you might need to consult your doctor on this one.


  2. Hey Mark,

    I have a very mild scoliosis. My pelvis slightly rotates to the left. when i straighten out my pelvis and rotate it slightly to the right to keep it straight, the right side of my rib cage flares out on the front and side of my core area. Now if I flex the right side of my abs / obliques my muscles seem to put the right side of my rib cage into the proper spot and my rib cage looks symmetrical.

    So my question is, should I mainly focus on doing ab and oblique exercises only on that right side that flares out? Or should i work both sides evenly?

    Thanks Mark!

  3. Hello Mark!
    Thank you so much for this information, you are for sure changing people’s lives with this information!
    I have super tight rounded shoulders from childhood, which has compensated into a ribflare where I am pretty much pulling my whole upper body forward and hyperextending/locking my knees. From that point, it seems like my left side scapula (my levitator scapulae) muscle has tightened and my left side of upper body is much higher than my right.
    X-ray shows that the rotation of my body indicates that the right side of the rib is much more flared than the left, but my tight left shoulder is providing another layer of rotation up top (my head is also rotated due to this)
    My physio has stated that I am unable to effectively breathe with my diaphragm and using my chest muscles to breathe (expansion of the rib is much greater than the stomach when breathing).
    I know there is a lot going on, but was wondering if you had any ideal how I would go about releasing that tight left shoulder. I have thoraic outlet syndrome type pain on the left shoulder and arm, and no matter what I do, I cannot let that left side to loosen up and hit the back muscles.
    That left shoulder seems to cause my whole body to rotate, and I am having problems all the way down to my ankles.

    Thanks alot for reading my problem, it has been a struggle for the past couple of years trying to find out what is going on with many medical professsionals.

    • Hey Mark, nice name.

      First things, I would recommend check to see if you have any rotation in your pelvis and/or spine. (as they can dictate the position of your shoulder)

      Make sure to check out the following 3 blog posts to see if they relate to you:

      1. Rotated Pelvis
      2. Twisted Spine
      3. Scoliosis

      In terms of how to release the left shoulder, simple trigger point, massage and stretch to the trapezius will help. But if you don’t correct the underlying issue, the tension will return.

      For your Thoracic Outlet Syndrome, please feel free to have a look at this post.
