Prevent injuries : Know how to curve your back

Ever got confused about how to curve your back in a certain type of exercise so you won't injure yourself? I've been there too, and I guess you're not alone in this situation. Let me get you out of this confusion right away. First, for the ones who don't have any back pathology, arching your back in some exercises doesn't involve any risk. On the contrary, if you do squats or deadlifts, where the spine tends to curve, arching your back may prevent new injuries. BUT, for some people, arching their back can turn out pretty unsafe.

                - For people suffering from spondylolysis ( non-union of the vertebral arch ), the extension of the lumbar spine may cause a sliding of the vertebrae ( spondylolisthesis ), which may badly compress elements of the nervous system ( which cause a sciatica ).

                - For people who have not yet completed their growth, or for people affected by osteoporosis, lumbar spinal extension  may cause a spondylolysis and a fracture of the vertebral arch. The vertebrae will be able to slide and badly compress the elements of the nervous system ( which cause a sciatica ).

Unlike the others muscle-development exercises, exercises for abs absolutely have to be done in vertebral winding. If you omit winding your back by contracting your abs and obliques, your hip flexors will accentuate the arch of your back by driving inter vertebral discs forward. This overpressure may lead to lumbago or worst, joint damage by shearing and compression.

I hope this will help to prevent you from having back injuries :)
