Thanks to the good people at Running Times magazine for allowing me to share this article/PDF on the site. The demonstrator is Kenyon Neuman, a young man who recently qualified for the 2012 US Olympic Marathon Trials.
The article explains my rationale for doing non-running activities before and after your run. The idea is that if you’re willing to commit 5 minutes (or less) before your run and 10 minutes after your run, the chance you’ll be injured decreases significantly.
You can download the article here; it’s 5.9 mb in size.
Finally, I’m indebted to Mike Smith for teaching me the principle that metabolic changes occur faster than structural changes. If you want to learn more, please visit RunningDVDs.com or watch some videos at the RunningDVDs.com’s YouTube channel.
