While looking for YouTube videos that demonstrated examples of proper running and walking gaits, I came across this video on Chi Running.
I'd come across the Chi Running book many years ago, but I unfortunately never looked into it. (I could've saved myself so much pain and discomfort while running.)
I've been exploring barefoot running for the past few years and as a result of running naturally, I've been discovering just how out of whack my body has become after years of improper running and walking, spurred on by, and no doubt contributing to, my bad posture.
If you run, even just a little, I strongly suggest watching this short video so you can understand how you may be, quite literally, putting the breaks on your progress.
There is so much we're not taught about how our bodies work and a little knowledge goes a long way towards avoiding injuries and correcting existing pains.
