Don’t stress your muscles and not stretch it, your body loves and needs a good stretch because it's not an option, it is part of your core training - so much so, that you need to do it before and after you train. We talk to Gantarvelocity about what good pre- and post-run stretch is made of and what it does to your body, the benefit of many recovery methods (massage! rollers! swimming!), and what to do with those tight muscles!
