Transverse Abdominis

Meaning

The Transverse Abdominis is the deepest and innermost of the three flat abdominal muscles, characterized by its muscle fibers running horizontally around the trunk, essentially functioning as the body’s natural internal corset. This muscle is the primary deep stabilizer of the lumbar spine and pelvis, playing a critical and non-negotiable role in generating intra-abdominal pressure and maintaining optimal postural integrity. Its proper function is foundational for efficient movement and overall Foundational Stability.
