I believe the answer is: Lifting
There are several things that must be followed to adhere to a safe lifting technique. The first one is to make sure that you have a proper grip on the object that you lift. The second one is to not bend or twist the waist during the lifting motion, your back and waist should always be straight. The last one is to keep your legs shoulders-width apart.
