The number one mistake people make when lifting, it actually involves two parts, is they will have some sort of bending motion at the waist along with reaching out from their body, to the left or right, to grab an object they are then trying to lift and bring closer to their body. Ok, so it was three parts. Imagine you are sitting in a chair and there is a box that is a couple feet in front of you and to your right. To grab this box without getting out of the chair you would bend forward at the waist and twist your upper body to the right to be able to reach the box. The problem is while bending at the waist and twisting, or rotating your upper body, you are stretching your back muscles close to their maximum amount, which makes them vulnerable to injury, especially if the box ends up being heavier than you were anticipating and you have to use those muscles more. Now you are really asking for trouble.
