When most people think of core workouts, they imagine crunches, sit-ups, and planks. However, if you’re still facing low back pain, poor posture, or instability—even after diligent workouts—your abs might not be the main issue. The problem often stems from a lack of deep core strength and stability.
At True North Physical Therapy, we empower active and driven individuals to rebuild their strength in ways that truly support their lifestyle—not just their workouts. Understanding the real mechanics of how your core functions is where we begin. Targeting deeper muscles makes a world of difference.
Understanding the Deep Core
Your deep core consists of a network of muscles that work together to stabilize your spine, pelvis, and ribcage. This system includes:
Transverse Abdominis (TA): A deep abdominal muscle that wraps around your torso like a corset.
Multifidus: Small stabilizing muscles found in your back.
Pelvic Floor Muscles: These support your organs and regulate pressure.
Diaphragm: Believe it or not, your primary breathing muscle is also part of your core.
These muscles engage reflexively with every breath and movement. They don’t just contribute to visual appeal; they also provide the foundation for your physical strength.
Why Surface-Level Core Work Falls Short
Traditional “ab workouts” such as crunches, leg lifts, or bicycle kicks focus on superficial muscles, like the rectus abdominis—the one that forms the iconic six-pack. While these muscles are important, they alone do not offer true spinal stability. It’s entirely possible to have well-defined abs and still experience pain, leakage, or postural issues.
Lacking stability from your deep core means that your body will recruit other muscles for support. For instance:
Your neck will tighten up when your breathing is shallow.
Your low back compensates, overworking to support unstable hips.
Your pelvic floor muscles may become overactive, leading to dysfunction.
This reliance on compensatory muscles leaves you vulnerable to injury, fatigue, and frustration.
Signs of Weakness in Your Deep Core
Are you noticing any of these signs?
Chronic low back, hip, or pelvic pain
Difficulty maintaining proper posture
“Doming” or bulging in the abs during movements
Urinary leakage during activities like lifting, laughing, or running
A sense of instability or lack of connection in your core
If these resonate with you, it may be time for a core reset—not just another round of crunches.
Steps to Enhance Deep Core Strength and Stability
At True North, we specialize in guiding our clients through deep core activation techniques. These practices establish a solid foundation for long-lasting strength and movement freedom. Here’s how we begin:
1. Diaphragmatic Breathing
Reconnect your breath with your deep core. Here’s a simple exercise to try:
Lie on your back with your knees bent.
Inhale deeply through your nose, allowing your ribs to expand.
Exhale slowly through pursed lips while gently drawing your belly inward. Repeat for 5 to 10 breaths, 1 to 2 times a day.
2. Engaging the Transverse Abdominis
Learn to activate your transverse abdominis. The goal is to pull your belly button toward your spine without holding your breath or crunching.
3. Implementing Functional Core Training
Once your foundation is stable, you can layer in more dynamic exercises, such as:
Bird dogs
Side planks
Glute bridges coordinated with your breath
Carriage and lifting patterns (like farmer’s carries or deadlifts)
The key is integration—using your core in ways that mirror real life.
It’s Not Just for Athletes or New Moms
While deep core strength is particularly beneficial for postpartum individuals, it is essential for everyone, including:
Desk workers struggling with back pain
Runners experiencing recurring injuries
Lifters aiming for better stability and form
Active moms who want to regain confidence in movement
Your core forms your center. When it operates effectively, every other aspect of your life becomes more manageable.
