Hala Asana or The Plough Posture is
a valuable asana as it has some unique qualities and excellent benefits. It is an extreme forward bending exercise
which promotes strength and flexibility in all the regions of the back and neck. 
It can be performed in two ways;
the only difference is in the position of the hands. Beginners can practice the
easier one which is explained in method 1.
How
to do :
Method 1
  - Lie flat on the back with your
    body straight and stretched out. Bring
    the heels and toes together. Put the palms on the floor and keep them close
    to the body on both sides.  
- Stretch out the legs and toes.
    Inhale and simultaneously raise both heads upwards till they come to a
    vertical position. 
- Exhale and simultaneously start
    lowering the legs towards the head area. Try to touch the floor in front of
    the head with the toes. Go only as far as possible for you. After exhaling,
    keep breathing normally till the whole posture is completed. Remain in this
    position for about 8 seconds. 
- Start returning the back to the
    floor. Let the back roll down on the floor inch by inch. This should be done
    very slowly and smoothly. Keep the legs and toes quite tight all along
    during the returning phase. Now you have completed one round of this posture
    and relax for 6 to 8 seconds. 
Method 2
  - Lie flat on the back with your
    body straight and stretched out. Bring the heels and toes together. Put the
    palms on the floor and keep them close to the body on both sides. Stretch
    out the legs and toes. 
- Inhale and raise both the hands
    upwards in a parallel way. Take the hands backward with the back of the
    palms on the floor. Finish inhaling at the time the hands have touched the
    floor. Exhale.
- Inhale and simultaneously lift
    both the legs upwards to a vertical position. 
- Exhale and simultaneously lower
    the legs towards the floor in front of the head and above the hands. Put
    your toes on the floor. If you cannot touch the floor with the toes, go only
    as far as possible. Breathe normally. Now you are in plough posture. In this
    position, your legs should remain straight and close to one another. Do not
    bend the knees and the arms, hands and palms should be parallel to one
    another. Remain in this position for about 10 seconds.
- The returning process should be
    done very gradually and in a controlled way. First return only the legs, let
    the hands remain on the floor. While returning the legs, let the shoulders
    roll back first and then the flanks, small of the backs, hip and lastly the
    thighs, legs and heels inch by inch. When the heels have touched the floor,
    lift both hands up and return them in a parallel way to the floor. Put the
    palms on the floor. Now you have completed one round of the best form of the
    plough posture. Relax for 6 to 8 seconds.
   
   Restrictions :
Start with one round on the first
