Proper form is a combination of two distinct fundamental ideas. The first fundamental idea is keeping your trunk in a neutral and stabilized position. What that means is, as you prepare to do any type of weight bearing exercise you have to make sure that your spine is aligned. That does not necessarily mean that it should be straight but aligned. The spine is the strongest when it is in alignment.
Stabilization is when the trunk muscles are working in unison to support the spine.
What that refers to is utilizing not only the proper range of motion of the muscle, but also the proper range of motion of the joint. Though they work together they are different. We must keep in mind that the chances of injuries increase as proper form decreases.
