How to push or Climb?
To push, pull or climb the stairs are few of the commonest
activities that is done in day to day life by all the individuals. The Degree
of ignorance is surprisingly enormous-and quite often a cause of backache.
While pushing an object (say grass cutter) one should not bend the back at the
hip joint and apply force with the arms held straight. The right way of doing
such an activity will be by keeping the back and the hips straight and bend the
arms at the elbow as shown in the illustrations below.
