We spend huge chunks of our lives standing for one reason or another. Standing exerts a lot of pressure on the spine especially if the individual is heavy. The pressure exerted on our spines will eventually start showing as we age. This is why it is quite important for an individual to try and ensure that they adopt the right posture every time they are meant to stand.
You should stand with one foot slightly in front of the other as this will help in distributing the weight. Your knees should also be slightly bent as this will help and relieve some pressure of the spine. You should also avoid bending the area around your waist forward. This usually ends up exerting pressure on the lower back muscles. When this happens for long periods of time then the person may start experiencing some serious back pain.
