Pulling your stomach in isn’t the same thing as engaging your deep core. And that difference matters.
When you constantly “suck in” your stomach, you’re mostly creating tension by drawing the abdominal wall inward with a shallow breath. It may make your waist look smaller, but it can also interfere with how pressure is managed throughout your core.
Think of your core like a pressurized cylinder. If you squeeze it in the middle, that pressure has to go somewhere—and it often gets pushed upward toward the diaphragm or downward into the pelvic floor.
Instead of simply pulling your stomach in, focus on creating pressure that is shared throughout the entire system.
Here’s what effective deep core engagement looks like:
• As you inhale, your diaphragm lowers and your pelvic floor naturally lengthens.
• As you exhale, your deep abdominal muscles (including the TVA) gently wrap around your trunk like a corset.
• Your pelvic floor responds by lifting naturally rather than being forcefully squeezed.
• Pressure stays balanced, giving you better stability and support from the inside out.
The goal isn’t to make your stomach look flatter—it’s to create a strong, coordinated foundation that supports your spine, your pelvic floor, and your movement.
A well-functioning core isn’t about holding your breath or sucking everything in. It’s about learning how your breath, diaphragm, abdominal wall, and pelvic floor work together.
