When people think about healing diastasis recti, they usually focus on exercises and splinting. However, one of the most critical components of core restoration is something you do thousands of times a day: breathing.
How you breathe can either support the healing of your separated abdominal muscles or actively work against it.
Your Core is Like a Pressure Cooker
To understand why breathing matters, you have to understand intra-abdominal pressure. Your core functions like a sealed canister. The diaphragm sits at the top, the pelvic floor at the bottom, and the abdominal and back muscles form the sides.
When you inhale, the diaphragm moves down, increasing pressure in the abdomen. When you exhale, the diaphragm moves up, and the pressure decreases.
If you have diastasis recti, the connective tissue (linea alba) at the front of the canister is stretched and weak. It is the path of least resistance. If pressure is not managed correctly, it will push outward against this weak spot, preventing healing and potentially widening the gap.
The Danger of Holding Your Breath
One of the worst things you can do for diastasis recti is hold your breath during exertion. Whether you are lifting a heavy box, picking up a child, or doing a challenging exercise, holding your breath traps the pressure inside the canister.
With nowhere else to go, that pressure pushes forcefully against the linea alba and the pelvic floor. Over time, this can worsen diastasis recti and contribute to pelvic floor dysfunction.
The Belly Breathing Myth
Many people are taught to practice "belly breathing" for relaxation, where the stomach pushes far outward on the inhale. While this can be relaxing, excessive belly breathing can be problematic for someone with diastasis recti.
Continuously pushing the belly outward stretches the already weakened connective tissue. Instead, the goal should be to manage the breath in a way that supports the core.
The Tupler Technique® Approach to Breathing
Proper breathing is a foundational element of the Tupler Technique®, a 4-step program developed by Julie Tupler, RN, to heal diastasis recti.
The program emphasizes:
- Exhale on Exertion: You must learn to exhale whenever you exert force. Exhaling reduces intra-abdominal pressure and naturally engages the transverse abdominis (the deep core muscle), pulling the belly inward and protecting the connective tissue.
- Lateral Rib Expansion: Instead of pushing the belly out, the Tupler Technique® encourages breathing that expands the ribs laterally (sideways) while keeping the transverse muscle engaged.
- Integration with Exercises: Breathing is meticulously coordinated with the targeted Tupler Technique® exercises to ensure maximum effectiveness and safety.
- Transverse Awareness: By combining proper breathing with transverse awareness, you learn to protect your core during every daily activity, from sneezing to standing up from a chair.
Mastering these breathing mechanics is essential for creating an environment where the connective tissue can finally heal.
What to Do Next
If you suspect you have diastasis recti, paying attention to how you breathe is a great first step. The next step is to learn a comprehensive approach to healing your core.

Frequently Asked Questions
Why is breathing important for diastasis recti?
Breathing regulates intra-abdominal pressure. If you hold your breath or breathe incorrectly during exertion, pressure builds up and pushes outward against the weakened connective tissue (linea alba), which can worsen diastasis recti.
How should I breathe to protect my core?
You should exhale on exertion. When you lift something heavy, stand up, or perform an exercise, exhaling while engaging the transverse abdominis helps manage pressure and protects the healing abdominal wall.
What is belly breathing, and is it bad for diastasis recti?
Excessive belly breathing, where the stomach pushes far outward on the inhale, can stretch the linea alba. The Tupler Technique® teaches a more controlled breathing pattern that expands the ribs laterally while keeping the transverse muscle engaged.
How does the Tupler Technique® incorporate breathing?
Proper breathing is a foundational element of the Tupler Technique®. It is integrated into the targeted exercises, transverse awareness, and body mechanics to ensure that intra-abdominal pressure is always managed safely.
