Diaphram, ISA, Breath

To all the incredible women out there—today we honor the powerful journey of motherhood and daughterhood, and the deep generational bonds we share with the women who came before us.

I often reflect on the remarkable truth that I was once inside my grandmother’s womb—as my mother’s eggs were forming, I was among them. Every emotional, physical, spiritual, and social experience that shaped her development also left an imprint on me. We are deeply interconnected, and the choices we make today ripple forward through generations.

With that in mind, I hope you’ll take time today to celebrate and care for yourself. Self-care is not selfish—it’s a gift to your grandchildren and to the future.
As I progress through my pregnancy, postpartum, and pelvic floor physical therapy course, I am continually amazed by how our bodies adapt and strive to keep us functional.
This week, we explored the diaphragm, breathing mechanics, rib angles, and their connection to diastasis and pelvic floor dysfunction.
Here are a few insights:

• A wide infrasternal angle (generally over 110°) may indicate susceptibility to diastasis. In this case, the diaphragm often shifts from a respiratory role to supporting the spine—due to imbalanced oblique and weak intercostal muscles.
• A narrow infrasternal angle (generally under 100°) can limit rib mobility, increasing intra-abdominal pressure and contributing to incontinence or prolapse. Breathing shifts to the upper chest, which may activate neck muscles and raise cortisol levels.
• Fascinatingly, the left side of the ribcage is usually wider than the right because the liver supports the right side.

What does all this mean? Simply put, breath is vital. Balanced strength and flexibility in our bodies begin with the way we breathe. The body is an incredible, interconnected system—from the top of your head to the tips of your toes.
Looking Ahead
Take care of yourselves, and I hope to see you soon as we continue to explore the balance between body and mind—together.
