I had a teacher in high school that would always say, “a dog never stretches before chasing after a car” meaning that you don’t need to stretch before going on a run. However, people seem to forget that the most important part of your run is how you warm up for it first. A good warm-up will help prevent a poor performance and any injuries during your run.
Whether you are running outside or on a treadmill, it is best to do a brisk walk before you start your run so you can warm up your muscles. When you’re running on the road you should walk 1-2 blocks. If you’re on the treadmill you should walk up to 5 minutes at 3-4 mph.
