You'll get immense pleasure while doing exercise/yoga

* when your stomach is empty.

* when you imagine that you are getting energy with every breath you take in; letting out all the impurities and toxins out of the body with every breath that you exhale.

* when you relax in between. Get all the benefits from the exercise, not fatigue.

A maxim of Hatha Yoga

" It is not what a man eats, but the amount that he assimilates, that nourishes him."
Eat nutrious and nourishing food, extracting the maximum amount of nourishment from the minimum amount of food.The stomach is a pear -shaped bag with a capacity of about one quart (1.136 litre or 2 pints). Fill your stomach 1/2 with food, 1/4 with water and leave 1/4 for the air. Miss a meal once a week to give rest to the digestive system.
