Answer 1

Lifting with your back has more chances of injuring you as opposed to lifting with your knees.
But also a way to prevent injury on certain parts of your body is to train them for specific activities.
While it is in bad form to lift with your back, there are times you cannot avoid it and those times if your back is properly trained injuries can be lessen or even avoided.
