Improving Posture - Can You Do It Without Exercise?

There seems to be no end to the questions about how someone might change their bad posture without exercise. Posture supports, posture aids, and posture vests are just a few of the things out there trying to convince you that you don't need exercise to help correct something that you exercised your way into.
I exercised my way into bad posture? Sure you did. You used your muscles (exercised) by simply doing your normal daily activities the same way over and over again. While you were performing some activities repeatedly, other activities were being ignored altogether. Your normal movements usually consist of things done in front of you, while the workout of your back muscles is holding you up. That would be fine if you were in an ideal posture position all day, but usually you're not. You slump, you slouch, and sleep in the wrong way.
Your back muscles got longer and longer and hence weaker and weaker until they were asked to do the same work or more under less than ideal circumstances. Now you are hoping to correct weak muscles by holding them in place? By keeping them from moving? They have to move to get stronger! Sometimes posture just seems like this big spine problem, so you think that it's just about the bones.
So it makes sense to you that if you can put braces on teeth, why not just hold you bones in place. Your bones are supported by your muscles and you need your muscles to work at their best to make a difference in how which position your spine holds. Muscles can become shorter or longer depending on the exercises and movements for which they are used.
While this works against you with bad posture, this is the key component to how you're going to get your posture to change. This also means that should you do a great job changing your posture and are looking good, if you return to the same activities that got you into your bad posture in the first place, your bad posture will return.
Your muscles respond to the activities for which they are used. If your job puts a strain on your posture, it's up to you to do the exercises to counteract what's been going on all day. You must exercise to change your posture, and that is a good thing.
