Sitting all day at a desk or computer station increases pressure on the lumbar discs in the lower back. Fluid circulation is necessary to get needed nutrients to these discs, so if the back isn’t moving around, neither are these nutrient-rich fluids. Orthopedic surgeons recommend 15 minutes of exercise each day that focuses on working abdominal muscles, back, hamstrings and fanny to reduce back problems triggered by prolonged sitting. Weight training can also help strengthen the lower back, therefore reducing potential pain. Doctors encourage regular exercise throughout the week to make life at the desk and in leisure activities to make life easier on your back.
