Everyone wants better posture. I bet after you read that first sentence, you sat up a little straighter, I know I did after I wrote it. People are looking for an answer, an exercise that will magically get them to sit upright and not hunch over their phone or computer. Unfortunately, that doesn’t exist.
Sure, we can do lots of horizontal rowing exercises to strengthen your upper back and teach you how to use your shoulders, but that won’t fix your posture while watching TV at night. You need to become sensitive to what you body is doing in order to improve posture. You have to constantly catch yourself and adjust your position.
Remember, there isn’t one static position that rules them all. We want to be moving and adjusting and spending sometime in all sorts of different positions. The key to improving your posture is awareness. Catch yourself and adjust, over and over and over.
