Now, squeeze your left foot similarly for a few seconds before allowing it to relax. In this way, slowly work on other parts of the body. Usually, muscle relaxation is started on the right foot, followed by the left foot, and then one has to move progressively upward. The usual sequence of this exercise is right foot, left foot, right calf, left calf, right thigh, left thigh, hips, and then you have to continue moving upwards from the buttock till you reach the face.
