Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.
4
Lift with your legs, not your back.
5
Keep the load close. The closer it is to your spine, the less force it exerts on your back.
6
Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid twisting your
body and back.
7
Follow the same techniques in reverse to set the load down.
