moving our body parts we create strain on skeletal
muscles. These movements are voluntary and we can
easily stop them and attain motion less posture.
This steady posture also cannot be maintained for
longer time as it also creates the strain because
we have to maintain the balance of our body. This
strain is minimum if we lie down on the bed or sit
comfortable on chair. This forms the preparation
for next stages.
It is not possible to stop the movements of internal
organs such as heart, respiratory system, digestive
system etc., but we can reduce the speed and thus
reduce the strain.
