In this example of a poor lifting technique, not only is the model poised to use her back instead of her legs to do the heavy work, but her back is also rounded. With a rounded back, the muscles are stretching, rather than contracting, which means they are not available to do the work of lifting. This position is especially problematic for people with disk injuries.
