If you aren’t incorporating dynamic stretching into your regimen, you should start. In this clip, triathlete and 2012 Ironman world champion Pete Jacobs takes us through 6 or 7 drills that are easy to incorporate. At least 2 or 3 times a week you should be doing some sort of dynamic stretching as well as static stretching. Warm up with an easy 10-15 minutes of jogging, then do your dynamic stretching. After you finish your run for the day, wrap it up with some static stretching. Better to shorten your run 5-10 minutes to fit stretching in than to run longer and not stretch.
