So, the key is learning how to make the most of the lung function that remains.
That doesn’t mean fixing damaged airways or regenerating destroyed alveoli — medicine cannot do that.
But the body has a natural advantage.
The diaphragm.
The diaphragm is a dome-shaped sheet of muscle that sits beneath the lungs.
In healthy breathing, it contracts and moves downward, creating a vacuum that pulls fresh air into the lungs.
When you exhale, it relaxes and rises, helping push air out.
In COPD, this process becomes disrupted.
Because the lungs are often hyperinflated and filled with trapped air, the diaphragm gets pushed down and flattened.
Instead of moving like a strong, flexible dome, it becomes stuck in a weak, flattened position, forcing you to rely more on the small muscles in your chest, shoulders, and neck.
These muscles are not designed to do the hard work of breathing, which is why people with COPD often feel constant fatigue, chest tightness, and struggle to take in enough air.
This is where diaphragm strengthening comes in.
By specifically training the diaphragm to become stronger and more efficient, it regains some of its natural dome-like shape and power.
A stronger diaphragm can generate more force with less effort, pull air deeper into the lungs despite obstruction, and help push out trapped air more effectively.
Over time, this reduces the sensation of suffocation, lowers the workload on accessory muscles, and makes breathing feel smoother and more controlled.
So how do you actually strengthen the diaphragm?
The same way you strengthen any other muscle in the body: through resistance.
Just like lifting weights forces your arms and legs to grow stronger, adding resistance to your breathing forces the diaphragm to work harder.
Over time, this targeted effort makes it more powerful and efficient.
This is where resistance breathing training comes in.
By creating controlled resistance every time you inhale, these exercises challenge the diaphragm, building its strength and endurance.
