When you sit, stand up, bend or twist, large compressive forces are applied to your spine. There are several factors that determine the ability of your inter-vertebral discs to handle these forces:
your inherited make-up
disc health - worsened by smoking, poor nutrition, sedentary lifestyle, weak muscles, and obesity
ageing
poor posture - while standing and lifting
heavy loads during activities.
