Q: I'm looking for a excellent book on weighttraining.have any suggestions?

A: The one indispensible book is Delavier's 'Strength Training Anatomy'. It is a superb reference for all the major muscle groups and exercises that most people will ever need. I highly recommend it. As far as different training programs, there're many good books with various training routines. The thing to keep in mind is that there's no such thing as THE best training routine -- customization, variety, and adjustments is what makes or break training programs and it's one of the major duties of a personal trainer to keep the routine continually challenging for the trainee. Stay away from books that make too-good-to-be-true claims or purport to provide the most effective training routines -- these are usually much more hype than substance. Having said that, Baechle and Earle's 'Fitness Weight Training' is a no-nonsence book that provides a variety of routines for various training levels and goals.
