As first teaching lesson in Judo begins with the fundamentals of Judo, I also thought to write book on Judo after teaching judo for more than 32 years to university level judo players. The Judo fundamentals are to be taught to any beginner for making his base strong, so that he/ she may be able to train himself or herself for international competitions in a better way after understanding the basic fundamentals. The teaching of fundamentals of Judo should receive great attention and importance by the Indian coaches. I have made sincere effort to enrich its content incorporating the latest information available with print and electronic media on various aspects of the fundamentals of Judo. The language being used is simple for better understanding of beginners and students of Physical Education undergoing professional courses of physical education in India.
