Simple twist is also known as parsva sukhasana, simple twist is very helpful in increasing the flexibility of the spine and upper back. It stretches the shoulders and upper chest while massaging the abdominals, thereby aiding digestion. This pose can be used for warming up as well as cooling down.
The hips should be evenly placed and the sitting bones should touch the ground. You can keep one leg bent and the other extended if you encounter any difficulty.
Twist and release the upper body before the pose will warm up the body and enable you to move deeper into the pose. Sitting on the edge of a couple of thickly folded blankets will let your knees drop so as to let you sit more easily. Keeping the hands on the top of the shoulders with upper arms parallel to the floor will open your chest more. Avoid this if you suffer from problems with discs in the back.
