Title: Richard Hittleman's introduction to yoga
First published: 1988
Description: I would describe this book as comprehensive,and a practical guide to hatha yoga and physical well being.
The book is paperback and well written.It illustrates each posture with simple articulant instructions.
It also explains the benefits,and objectives of the various postures.
Unlike resistance exercise,push ups etc.when doing any stretching or postures 
being gentle and non-forcefull produces the desired result of vitality,and well being.
