Poor posture can be associated with a high proportion of back problems. When we sit in a slouched position, we lose the S shape and this can cause us discomfort. Sitting for prolonged periods of time reduces blood flow, which is why it is so important to change the posture.
Standing in a bent position is also an undesirable posture. The best posture is one where the body is upright and symmetrical, not twisted.
Regular exercise can help compensate for the lack of activity during the day. Strong muscles will help the bodywork more efficiently than weaker ones. Flexibility is just as important as strength in helping us perform well, not only at work but in our leisure time as well.

Pushing and pulling correctly is as important as lifting correctly. The best way to push is to put your back against the load and use the thigh muscles. If this is not possible, keep the back straight to reduce the stress on the spine. Do not over reach, stay close to the load. |
Pulling generally puts less stress on the spine than pushing. When pulling, keep a straight back use your legs. So not, jerk the load. Do not over reach, stay close to the load. |
The most efficient height at which to lift is between elbow and knuckle height when standing with the arms by the side. Lifting above shoulder height and below knee height is only recommended when lifting loads that are a lower weight.
