What is posture anyway?
When we were younger, we were often told to sit or stand up straight. In those days, this may have been mostly a matter of good decorum. However, good posture is not just a matter of good manners. It is much more than that.
Posture refers to the way in which your body is positioned when you are sitting, moving or standing. As well as being vital for our movement and comfort, having good posture means that muscles and ligaments are not working harder than they should.2
Posture helps keep your body erect. It can also, to some degree, ensure proper breathing, muscle growth, and movement.3 Additionally, it can help alleviate some body pain. Poor posture can affect your health overall, and set you up for neck and shoulder strain, back pain and even joint damage.4 This is why practicing good posture is important.
There is an aesthetic aspect to good posture, as well. That hunch neck and potbelly may just go away once you start sitting and standing up straight and stop slouching.
