2. Stretch.

I know, I know, you’ve heard this one, like, a zillion times. But check this out: Most trainers nowadays say that you’re not supposed to do static (standing still) stretches before your workout—only after it’s done. Warm up with dynamic movements, like walking or jumping jacks, and do the lunge and calf stretches after your run (or during breaks while on your run). I was also told I should get a foam roller to do IT-band therapy. This will save you from knee injuries as well. From what I understand, it hurts like a hole in the head, but in a good way.
