How Muscle Imbalances Create Chronic Low Back Pain

In this episode, Dr. Ryan Peebles, Doctor of Physical Therapy and founder of Core Balance Training, explores how predictable muscle imbalance patterns, not isolated injuries or “bad posture”, drive most cases of chronic low back pain. Dr. Ryan explains how the body enters a full-body protection pattern after injury, stress, or prolonged sitting, and why this pattern pulls the spine into exaggerated curves that reinforce pain, stiffness, and instability. Referencing Vladimir Janda’s Crossed Posture Syndrome, he breaks down how tight hip flexors, weak glutes, inhibited core muscles, and overactive spinal extensors work together to keep the body stuck in pain. Through detailed coaching responses, he explains why setbacks happen, how fear-based movement patterns limit recovery, and how rebuilding core-driven movement restores confidence, balance, and long-term spinal resilience.   This episode covers:   Why most chronic back pain follows a predictable, full-body postural pattern How protection mode pulls the body toward a fetal position The role of exaggerated spinal curves in ongoing pain Why hip flexors tighten and glutes shut down in chronic pain Why massage and adjustments often provide only temporary relief How core weakness drives compensation and instability The connection between hip pain, back pain, and movement retraining   Watch the free Core Balance Masterclass and start your 7-day free trial to experience the Back Anchor lesson firsthand and begin retraining your movement patterns from the inside out: https://www.corebalancetraining.com/masterclass    Disclaimer: All content is for educational purposes only.
