Posture isn’t just an aesthetic concern. Yes, people do judge you based on the way you stand and hold yourself, but that isn’t the only reason it’s important. It’s also important because it shows you how your muscles are working.
When muscles in the front of your body are too tight and short, you slump and slouch. When muscles on the right half of your body are too weak to do their jobs, you tend to slant to the left. If muscles of the back of your shoulders and neck don’t do their jobs, you end up with shoulders hiked up to your ears and a head that juts forward.
A quick assessment of your own posture gives you immediate clues to how balanced your muscles are functioning. One shoulder high? One shoulder low? Hips twisted? Head forward? It can be corrected.
You just have to take the time to do it.
