In the hips, the hip flexors maintain tension to prevent the torso from collapsing backward, while the gluteal muscles provide a stable base for the pelvis. Anterior pelvic tilt, where the front of the pelvis drops and the back rises, flattens the lumbar curve and strains the lower back.
Sitting Anatomy Compression Effects on Muscles and Posture
The core muscles, including the transverse abdominis and the erector spinae, work continuously to stabilize the trunk. These adjustments are managed by a complex interplay of muscles, ligaments, and joints working to keep the center of mass aligned over the base of support.
Erector Spinae: These muscles run along the spine and are responsible for extending the back and maintaining upright posture. Hip Flexors: A group of muscles that connect the thigh bone to the pelvis and lower back, crucial for lifting the knees toward the chest.

Conversely, posterior pelvic tilt, where the pelvis rocks backward, can cause the upper body to hunch, placing stress on the thoracic spine and shoulders. Key Muscular Players Several muscle groups are actively engaged to maintain an upright position in a chair.
