What is a Herniated Disc?
Normally the disc is a very strong structure that can withstand excessive amounts of compressive loads that occur with exercises such as the deadlift as long as proper form is maintained.
Repetitive strain due to poor lifting mechanics, excessive bending forward, twisting, sitting and poor core function (different than strength) can cause the outer tough layer to tear. Once enough of the layers are torn through, the center fluid (nuclues propulus) pushes on the weakened wall. This is one mechanism of a disc bulge, herniation or it’s nickname the slipped disc.
