We all heard ‘Always bend your knees when lifting’, but do we follow this advise?

Dr. Robert S. Renfro explains that a great portion of back problems are simply due to tension and muscular tightness, which come from poor posture, inactivity, being overweight, stress and lack of abdominal strength.  A normal lumbar curvature or lordosis is 35 degrees, with the normal cervical lordosis being 45 degrees (see Correct Your Bad Posture).  The muscles involved are the abdominal, hamstring, quadriceps, gluteal and lower back muscles. These muscles need to be of equal length and tone on both sides. If there is an imbalance, this can cause pelvic rotation of the ilium and sacrum.
