How to Fix Poor Posture Caused by Over-Arching the Low Back

I’ve gotten quite a few questions lately about anterior pelvic tilt and what to do about it if it’s your posture pattern.

An anterior pelvic tilt happens when your ASIS (anterior superior iliac spine) the top, front of your hip bones) tilts forward which increases the curve of your lower back.

This is definitely a position you want to be able to move your pelvis into and out of, but it’s not one you want your pelvis to stay in all of the time.

When your pelvis is in a constant anterior pelvic tilt, the bottom ring of your ribs doesn’t line up with the top ring of your pelvis. This changes your intra-abdominal pressure and how you are able to breathe. Over time this creates problems such as:

  • back pain
  • chronic tightness
  • pelvic floor dysfunction
  • difficulty accessing deep abdominals
  • head shear
  • muscle compensation

When you lie on your back, if you have more than a fingertip’s space between your low back and the floor, your pelvis could be tilted too far forward and you may be unknowingly creating more tightness in your body when you exercise.

I’ve seen the tip in today’s video change people’s alignment for the better over and over again. And the best part is that it’s very simple and once in place you don’t have to think about it.

I’ve been impressed with how quickly this simple tool can improve your ability to move and connect to deeper muscles.

Watch the video and, if you try it out, or have any questions, let me know in the comments below.
