Why practice Yoga exercises?

When it comes to achieving both physical and mental well-being, Yoga exercises are by far the most effective and time-tested practices known to mankind.  Yoga asanas effectively strengthen and tone the body, increase flexibility, improve balance, and relieve stress.  However, the most significant benefits of yoga asanas come from their profound effects on the internal systems of the body.

By bending, stretching, twisting, and flexing in the various postures, you bathe your internal organs with oxygenated blood and prana, also known as "life force energy" or "chi." 

Yoga asanas soothe and tone the nerves and regulate the endocrine system, which is responsible for the production of hormones - one of the keys to both physical and mental health. They also improve digestion and elimination, strengthen the respiratory system, and tone the reproductive organs.
