Revealed: When You Stop Sucking In Your Tummy — The Magic Happens

October 30, 2025

Here’s the truth:

There’s a direct link between pressure, core, and pelvic floor function.

Think about it —

  • Prolapse is a pressure issue
  • Hernia is a pressure issue
  • Abdominal separation (diastasis recti) is a pressure issue

Understanding Pressure in the Body

The human body has three main cavities:

  1. Thoracic cavity (chest)
  2. Abdominal cavity
  3. Pelvic cavity

When there’s too much pressure in one cavity compared to the others, the body experiences an imbalance of load — and this imbalance happens with every single breath you take.

There are only three directions that pressure can go:

  • UP – into the thoracic cavity, toward the diaphragm → may contribute to a hiatal hernia
  • OUT – through the abdominal wall’s weak points (like the belly button) → can cause diastasis recti or an umbilical hernia
  • DOWN – toward the pelvic floor → often leading to pelvic organ prolapse or pelvic floor muscle dysfunction

What Happens When We Stop “Sucking In”

When clients come to me with pelvic floor dysfunction, something amazing happens:

By working on their alignment, addressing muscular imbalances, and teaching pressure awareness, breathing mechanics, and better movement habits, they don’t just feel relief — they also get stronger through their core.

And here’s the kicker:

I achieve all this without ever telling them to “suck in your abs,” “engage your core,” or “lift your pelvic floor.”

My Full-Body Approach to Pelvic Health

Because prolapse, hernia, and abdominal separation are all pressure issues, I look at the whole body to identify and prioritize what needs attention first.

Here are some of the first things I explore:

Bathroom Habits

Are they straining to wee or poo?

Would a “knees above hips” setup — like a Squatty Potty — make things easier and more natural?

Foot Mechanics

How are their feet functioning?

  • Do they turn out when walking or standing?
  • How much dorsiflexion do they have?
  • What kind of shoes do they wear most often?

Feet are the foundation of alignment — and they influence everything above them.

Glutes and Hamstrings

Are they a butt gripper?

Or do they have no visible glutes at all (which might indicate tight hamstrings)?

If so, before focusing on “strength,” we first need to restore length to those tight muscles to create balance in the chain of movement.

Breathing Mechanics

How do they breathe?

If it’s classic belly bracing or shallow chest breathing using the neck and shoulders, we start by retraining their breath.

A simple cue like “blow out through your mouth as you lift” can re-engage the diaphragm, activate the core, and naturally lift the pelvic floor.

Breathing is a huge piece of the pressure puzzle.

Movement and Lifestyle

How much are they moving in daily life?

If walking or natural movement is limited, I’ll often start there. Walking helps:

  • Strengthen the glutes
  • Improve gait and posture
  • Support pelvic floor function

It’s one of the simplest, most effective ways to integrate all the puzzle pieces together.

In Summary

There you have it —

A whistle-stop tour of just some of the factors I focus on to improve reflexive core function and reduce the likelihood of hernias and prolapse.
