Lift with your legs, not your back!

Many bulding and herniated disc can be attributed to lifting objects incorrectly. When picking up an object from the floor, bend at the knees, keeping the spine as erect as possible. Rise using the strenght of your legs, as their simple and sturdy architecture is designed for such exertions. Putting great amounts of pull or pressure on the spine when bent forward or backward can compromise its delicate alignment. 

Of course, there is no right way to lift an object that is simple too heavy. Listen to your body, and if you feel any  discomfot while doing heavy lifting, back off and save your back.
