Protect Your Upper Body

Your pelvis supports the weight of your upper body while sitting and standing. The pelvis consists of a group of muscles that attach to the front, back and sides of your pelvis and your tailbone. These muscles support the pelvic organs. When these muscles are tight or spasm, your pelvis can feel great pain.

Understanding The Pelvis

All of the muscles of the pelvis come together at the sacrum to form a ring shape, which also connects to the hip joint. Muscles and ligaments surround the pelvis to keep it stable as the rest of your body moves. There is also a small amount of movement that occurs at the sacroiliac (SI) joint, which is the connection of the sacrum to the iliac portion of the pelvis. The SI joint can be injured during exercises like a thruster or deep squat because unnecessary forces are placed on it when midline stabilization is lost.

Major muscles of the pelvis:

  • 2 ilium
  • 2 ischium
  • 2 pubic bones

Motions of the pelvis:

  • Anterior pelvic tilt
  • Posterior pelvic tilt
