Strong Core, Healthy Back: How Core Strength Protects Against Back Pain

Back pain is one of the most common reasons people search for help online or visit a physical therapist. In fact, nearly 80% of adults experience back pain at some point in their lives. What many don’t realize is how closely core strength and back pain are connected. Strengthening your core doesn’t just improve posture or athletic performance—it’s one of the best ways to protect your spine and prevent recurring pain.

What Is the Core, Really?

When most people think of the core, they picture six-pack abs. But your core is much more than just your abdominal muscles—it’s a network of deep stabilizing muscles that surround and support your spine. These include:

• Transverse abdominis – your body’s built-in “weight belt” that provides spinal stability.

• Multifidus – small muscles along the spine that keep vertebrae aligned.

• Obliques – help with twisting and side-bending.

• Pelvic floor muscles – provide support from below.

• Diaphragm – works with your abs and breathing to stabilize your trunk.

• Glutes – powerful hip muscles that are essential to core strength.

  
  

When these muscles aren’t activating properly, your lower back is forced to absorb extra stress. Over time, this often leads to chronic back pain, stiffness, and even injury.

How Weak Core Muscles Lead to Back Pain

A weak or unbalanced core often creates what physical therapists call “compensation patterns.” Your body finds shortcuts to get the job done, but they usually put more strain on your back. Common issues include:

• Overusing the lower back muscles instead of relying on the core and glutes.

• Tight hip flexors from sitting too much, which pull the pelvis out of alignment and increase back strain.

• Shallow breathing patterns that neglect the diaphragm, reducing spinal stability.

  
  

Over time, these faulty movement patterns can lead to recurring pain, poor posture, and limited mobility.

3 Physical Therapist-Approved Core Exercises for Back Pain Relief

Not all core workouts are created equal. Crunches, for example, mostly work surface-level abs and can actually make back pain worse. Instead, focus on exercises that build stability and strengthen the deep muscles that support your spine:

1. Dying Bug/ Dead Bug

   • Lie on your back with arms extended toward the ceiling and knees bent at 90 degrees.

   • Slowly lower the opposite arm and leg toward the floor while keeping your lower back pressed down.

   • Return to start and switch sides.

   • Why it helps: Builds core control and protects the spine during movement.

2. Bird Dog

   • Begin on hands and knees.

   • Extend one arm forward and the opposite leg back, keeping your hips level.

   • Hold for a few seconds, then switch sides.

   • Why it helps: Improves spinal stability and coordination.

3. Glute Bridge

   • Lie on your back with knees bent and feet flat.

   • Press through your heels to lift your hips, squeezing your glutes at the top.

   • Lower slowly and repeat.

   • Why it helps: Strengthens the glutes and core, reducing strain on the lower back.

     
     

These exercises target the deep stabilizers, making them essential for both back pain prevention and recovery.

When Should You See a Physical Therapist?

If you’ve had back pain for more than two weeks, or it keeps coming back despite stretching and exercise, it’s time to seek professional help. A physical therapist can:

• Assess your movement patterns.

• Identify weak or imbalanced muscles.

• Create a customized program to strengthen your core and protect your back.

  
  

Unlike generic workouts, physical therapy provides tailored strategies for lasting relief.
