Accessory Rib Flare Exercises

What’s A Rib Flare?

A rib flare is a condition of your posture. Rib flares consist of:

  • an excessively straight upper back
  • an overly curved lower back 
  • an elevated chest with lower ribs sticking out. 

Rib flares change the position of your rib cage in relation to your pelvis. 
It causes your torso to shift forward of the pelvis when standing.

The ribs normally should be down and in a neutral position. This is perfect for your diaphragm to work best. 

A rib flare extends the diaphragm and prevents you from taking full, deep breaths. 

Corrective Rib Flare Exercises

Rib flare exercises are essential for promoting better posture and breathing better. These exercises work because they improve rib cage expansion. 

The idea is that there’s more space for the rib cage to expand in the back of the rib cage than the front. 

By improving rib cage expansion from the back, you can get rid of lower rib flare and improve your breathing.

  • The first and most important thing is a full, long exhale. Softly exhale through your mouth like a long sigh. 
  • Have your mouth open and softly exhale for 5 to 10 seconds. 
    Feel your ribs come down, and at the end feel a bit of side ab tension. 
  • After you feel the side abs tense, close your mouth, and silently inhale through your nose. You should feel the rib cage open up. 
  • A silent inhale ensures that you’re using the diaphragm. Loud inhales use more neck muscles, and you want to reduce that as much as possible.

  • Lift your hips off the ground
  • Focus on lifting your rib cage towards the ceiling
  • You’ll feel a side crunching sensation
  • Hold the position for 15-30 seconds on each side for 2 sets 


The plank is an excellent overall core strengthener and stabilizer. It can be done by itself or in a moves like a push up or mountain climber.  

  • Get into a push-up position with your forearms on the ground
  • Keep your head in a neutral position, looking down at the ground
  • Keep elbows directly beneath your shoulders
  • Your body should form a straight line from head to your heels

  • Tighten your core and squeeze your butt

  • Breath evenly and deeply

Rib Cage Compression Breathing 

This exercise helps to improve ribcage control and muscle engagement.

  • Stand with your feet shoulder width apart

Stretching them is a good idea to open up your back. 

  • Stand facing a sturdy doorway
  • Keep feet hip-width apart
  • Lift your arms overhead and extend them straight up
  • Bend your elbows at a 90-degree angle, with palms facing forward

What’s The Problem With Rib Flares?

When rib flares are not dealt with, they can result in bad posture, muscular weakness, aches and pains, and eventually difficulty breathing.

Rib flares may also be noticeable under clothes and affect your body image. 

Rib flare exercises can be done to correct posture and improve the way you feel about yourself.

Rib flare exercises may help alleviate pain and get you back to normal torso position. 

Rib Flares and Posture 

Rib flares affect more than the lower ribcage. It has a chain reaction effect on your entire upper body posture. 

Tell tale physical signs of a rib flare are 

  • Elevated chest 
  • Super straight upper back
  • Shoulder blades extremely pulled back
  • Ribs that jut out excessively when you raise your arms
  • Overarched and tight lower back 
  • Possibly an anterior pelvic tilt  

Wait. Chest out, back straight, and shoulders back sounds like good posture. What’s the problem here then?

Good posture involves having your shoulders down and back. But rib flares pull shoulders back, and prevent them from depressing (dropping down). 

The upper back has a natural forward curve and should not be overly straight, like with an elevated chest. 

Rib flares increase the tension in your lower back and mid back muscles, and misalign your pelvis. This can cause you to be more injury prone and have balance and stability issues. 

Rib Flares and Core 

Rib flares result in an over extension of the stomach or core.

The core acts as a stabilizer and keeps your body tight while sitting, standing, and doing everyday activities. It provides much needed support for the spine. 

  • If the lower back is overarched, that means the abdominal muscles are overstretched. 
  • This limits and weakens the core to the point where it leaves your lower back unprotected. 
  • When the core is over extended, other back muscles have to compensate. The back muscles and hip flexors have to work and strain harder. 

Rib Flares and Breathing

When we normally inhale, our rib cage should expand in all directions. 

It expands front to back, side to side, and our stomach rises simultaneously. If your rib cage doesn’t expand then there’s a problem.

That’s because our lungs are in our rib cage and they need to expand when we breathe. 

We find a way to compensate for the rib cage not expanding through the path of least resistance. The way this is most often done is by moving the lower ribs up and out of the way. 

  • Rib flares make it so that your diaphragm cannot fully contract. When this happens, taking deep breaths is very difficult. 
  • The diaphragm normally contracts by flattening and moving down when we inhale. This causes your chest to rise and lungs to expand and fill with air. 
  • With a rib flare, the chest is already elevated so that space that’s needed for expansion is not there. 

Rib Flares and Aesthetics

You may have a rib flare that alters the way shirts look on you. 

This can affect your self-esteem, and chances are you may want to hide it as much as possible. Some tips to do that are: 

  • Wear shirts the are less form fitting in the waist area
  • Wear darker colored clothing
  • Don’t bring attention to the waist with flashy belts
  • Wear layers to add bulk over the area 

What Causes Rib Flares? 

Understanding the causes of rib flares will address the condition. Rib flare exercises can help to reverse it. Causes of rib flare include: 

  • Genetics. Some people are born with a rib cage that sticks out, or that is more likely to get a rib flare. You can’t change genetics, but you can work on posture and making muscles strong. 
  • Chest breathing. Stress and anxiety can cause you to take shallow breaths. Shallow, fast breathing comes from high in the chest and not from the diaphragm. Too much of this can cause rib flare. 
  • Muscle weakness. Lack of physical activity and prolonged sitting can contribute to rib flare. A sedentary lifestyle can create weak abdominal muscles. 
  • Injury. If you’ve been hit in your chest region in sports or fighting, this can cause rib flare. 

Other Lifestyle Adjustments
For Rib Flare 

Fixing rib flares doesn’t stop with just rib flare exercises.
You can do little things on the regular and take preventative measures. 

  • Mindful Posture. Become more aware of your posture while walking, standing, or sitting at your desk. There’s posture correction products you can try. 
  • Ergonomic Workspace. Invest in a chair that’s good for you back. Adjust your desk and monitor to minimize strain. Buy a laptop stand if you need. 
  • Move Regularly At Work. Take short breaks every 60 minutes. Get up and walk or stretch to wake up those muscles. Light cardio on rest days can also help to get moving.

Bottom Line 

Now you enjoy the corrective benefits of rib flare exercises. Better posture, improved core strength, and reduced back pain can be yours. 

As you incorporate these rib flare exercises and lifestyle adjustments, you’re investing in your health and well being. 

So stand tall with confidence and breathe easy with the positive changes!
