What Are Core Muscles?
Core Muscles are the muscles surrounding the trunk and pelvis that help support the spine, control body movement, and maintain balance. They include muscles in the abdomen, back, hips, and pelvic region. These muscles work together during activities such as standing, walking, lifting, and changing position.

Key Takeaways About Core Muscles

- They help control posture, balance, and spinal movement.
- Core strength is not the same as visible abdominal definition.
How Core Muscles Works

Core muscles coordinate activity around the trunk and pelvis. The abdominal wall, back muscles, hip muscles, and pelvic floor can share the work of stabilizing the spine during movement. Their activity changes with the task, body position, and direction of force.

During a squat, for example, these muscles help keep the trunk controlled while the hips and legs move. A clinician may observe breathing, posture, balance, and movement quality to understand how the core responds. The lumbar spine and pelvic floor are often considered when assessing how trunk support relates to back movement.

From the Arrowhead Clinic Chiropractor Garden City team
When we evaluate core muscles during Back Pain Treatment, we observe how the trunk, pelvis, and limbs coordinate during ordinary movements. We consider breathing, posture, balance, and muscle control together. This approach helps us distinguish limited coordination from a problem involving strength alone.
Core Muscles in Practice: A Real-World Example
A person with back pain may brace the abdomen while rising from a chair, yet still shift the trunk unevenly. During an assessment, the clinician observes that movement pattern and considers how the core, hips, and spine work together.
