When people think about strengthening their lower back, they often picture big, powerful muscles like the erector spinae or focus on traditional core work like planks and crunches. But what if the real key to spinal stability and lower back pain prevention lies in something much smaller—hidden deep within your back, quietly working behind the scenes?
Enter the multifidus, one of the most overlooked yet crucial muscles for spinal health. Alongside other deep stabilizers, this muscle plays a vital role in strength, control, and pain-free movement. If you’re serious about protecting your back, improving everyday performance, and enhancing overall strength, understanding and training these muscles is non-negotiable.
Meet the Multifidus: Your Spine’s Silent Guardian
The multifidus is a series of small, deep muscles that run along the vertebral column, attaching from one vertebra to another. Unlike larger muscles that create big, visible movements, the multifidus is all about stability, control, and micro-adjustments.
Here’s why it’s so important:
✅ Spinal Stability: It keeps the vertebrae aligned, preventing excess movement that can lead to pain and dysfunction.
✅ Injury Prevention: A strong multifidus absorbs and redistributes force, reducing strain on the lower back.
✅ Automatic Activation: It fires before movement even begins, anticipating and supporting every motion.
✅ Pain Reduction: Studies show that a weak or inactive multifidus is linked to chronic lower back pain, making it a critical area to target.
In short, the multifidus is the glue that holds your spine together—but if you’re not training it, you’re leaving a major weak link in your strength chain.
The Role of Small Spinal Muscles in Strength and Pain-Free Movement
The multifidus doesn’t work alone. It’s part of a deep stabilizing network that includes:
🔹 Rotatores & Interspinales: Tiny muscles that fine-tune spinal movement and provide proprioception (your body's sense of position).
🔹 Transversus Abdominis (TVA): A deep core muscle that works with the multifidus to create internal pressure and support the spine.
🔹 Pelvic Floor & Diaphragm: Key players in spinal stability, breath control, and lower back support.
When these muscles activate properly, they create a solid foundation for movement. When they don’t? Your larger muscles compensate, leading to stiffness, imbalances, and an increased risk of injury—especially in the lower back.
Why You NEED to Train the Multifidus
A weak or inactive multifidus can spell disaster for your lower back. Here’s what happens when these muscles aren’t doing their job:
❌ Increased Risk of Lower Back Pain: Weak stabilizers lead to excessive movement between vertebrae, causing strain and discomfort.
❌ Compensation Patterns: Other muscles take over, leading to tightness, stiffness, and imbalances that limit mobility.
❌ Decreased Power and Strength: Without a stable spine, force transfer is compromised, making you weaker in lifts, runs, and everyday activities.
But here’s the exciting part: You can wake up and strengthen these muscles with the right training.
How to Activate and Strengthen the Multifidus (And Why Traditional Core Work Won’t Cut It)
The multifidus does not respond well to traditional “core” exercises like sit-ups or back extensions. Instead, it thrives on low-intensity, high-control movements that improve coordination and endurance.
Try these multifidus-focused exercises to build spinal stability and reduce lower back pain:
✅ Quadruped Opposite Arm/Leg Raises (Bird Dog): Helps train the multifidus to stabilize during movement.
✅ Supine Marches with TVA Engagement: Strengthens deep core muscles and enhances spinal control.
✅ Segmental Cat-Cow: Improves spinal proprioception and small muscle activation.
✅ Hyperextension Holds And Reps (Small Lifts): Targets the deep stabilizers without compensation from bigger muscles. (We learn this in Phase Two)
The goal is not brute strength, but fine-tuned control. Focus on slow, controlled movements, breathing, and feeling the muscles engage properly.
The Next Step: Mastering Multifidus Activation
If you want real, lasting lower back strength, it’s time to look beyond the big, flashy muscles and start paying attention to what’s happening deep inside your spine.
By training the multifidus and other small stabilizers, you create a bulletproof foundation—reducing pain, preventing injury, and unlocking new levels of strength and performance. But first we must balance out other muscles which is covered in Phase One of LBM.
In Phase Two of our LBM Program, we go even deeper into these stabilizing muscles, refining activation techniques, advanced stability drills, and progressive loading strategies to ensure long-term spinal health and resilience.
So, before you add more weight to your squat or push through another round of sit-ups, ask yourself: Is your spine truly stable? Or are you building strength on a shaky foundation?
Train smart, train deep, and take control of your spinal health—because when it comes to lower back pain prevention, the smallest muscles make the biggest difference.
