Active Isolated Stretching has helped me out in big ways.   I have been running competitively for 30+ years and have never been able to stand, bend over and touch my toes. after 3 days of 2 AIS routines/day, I was able to touch my knuckles to the ground.  Big changes.    It is a different kind of "stretching" than the typical, static stretch and does so much more.

Here is a link to a Running Times (the best serious runners mag out there) article on Phil Wharton, who has been treating professional athletes for a while now with this method: Phil Wharton, Peace Through Strength.
enjoy.

Here is his Website where you can learn all about his methods and stretching routines:  whartonperformance.com
Strengthening is a big part of his program as well and should not be overlooked.
There are videos galore and I highly recommend them.
