tl;dr
I offer my 10 best quad stretches. We discuss why your quads or hips might feel tight and why your hip or knee might hurt. We talk about when stretching isn’t the best solution for pain. I offer alternatives to stretching that might better solve your problems. We talk about the negative and positive side effects of stretching. We even talk about seemingly unrelated causes of quad tightness. I leave you with a short appendix on the pertinent anatomy (because what else would you expect from someone with a masters degree in anatomy?).
