The importance of controlled hip mobility

In "The importance of controlled hip mobility", by Micheal Davis, discusses many issues of hip mobility.  The first most thing that stood out to me in this article, was the amount of time that we spend sitting.  Our daily lives require us to sit for hours.  Sitting in a classroom all day or at work all day (over and over) causes out ligaments and muscles to shorten.  This results in decreased hip mobility.  This lack of flexibility causes an anterior tilt at the pelvis and puts more stress on the lower back.  And we wonder why lower back pain is so prevalent these days?  The higher you move up in the world, the more you get to sit.

I also found it interesting that most commercial gym equipment has the athlete sitting while performing the exercise.  These machines don not allow for full hip extension.  I never thought of this problem before.  Seated row, seated chest press, seated.....seated,......  The list can go on and on.  Although people are getting in the gym, they are not really gaining better hip mobility.  Hip mobility is an important aspect to any individual's workout and it should not be avoided.
