The title reflects my initial reaction to someone who first introduced me to some running techniques. I thought, "Running is the most natural form of exercise out there, unless you consider breathing to be exercise, so what is there to know?" In fact, there is a few tidbits about technique that I think every runner should know. As a disclaimer, every runner has a different style of running unique to their own build and body type so take what I've found out about running technique and fit it to you and how you run.
Sit Up Straight!
Relax?! Relax?! How am I suppose to relax when I'm hard at work trying to make it through the next mile? What I mean by relax is that you don't need to tense up muscles unnecessarily. During one of my first runs I noticed my shoulders ached quite bit. Some of that had to do with improper breathing techniques (see above) but it also had to do with tensing the wrong muscles. While running, resist clenching your hands into fists, relax your shoulders, and leave your mouth slackjawed. You'll still have plenty of muscles at work for you, but having too many muscles working for you will only make things harder. Clenching your hands into fists will tense muscles up and down your arm, leading to sore shoulders. Relaxing your shoulders will save, obviously, your shoulders, but also your back from unnecessary strain and leaving your mouth open will allow neck muscles to relax during your run.
I've watched this video countless times to get this technique down. I still don't have it down, but when I focus on it, I can pull it off for a while but then my thoughts wonder and I slip back into heels first running. So I'm still practicing. But when I am doing the Pose method, I feel a load taken off my legs and I immediately run faster with little effort. So it's worth the practice in my mind.
So there you go. That's how you run. I'm sure that there are probably more techniques out there that I haven't heard of or explored, but these seem to be the key essentials and ones that I practice. Let me know if you guys want to add anything here; things that you may have discovered while running.
