In order to build the muscles in your upper body, lower body, and core, you need to spend some time in the gym. However, working one additional muscle can help you obtain even better results: your brain.Reading about muscle building enables you to learn more about exactly what you need to do to get you the positive results you desire. With that thought in mind, here are three of the best muscle building books available: The Book of Muscle: The World’s Most Authoritative Guide to Building Your BodyThis book, authored by Lou Schuler (Men’s Health fitness director) and Ian King (Australian strength coach and former powerlifting champion), sets out to answer all of your questions about how to build a bigger, stronger body—from what to eat to which exercises will give the best results. It also has three different six-month programs if you’re ready to start your own. The New Encyclopedia of Modern Bodybuilding: The Bible of Bodybuilding, Fully Updated and RevisedWho knows more about bodybuilding than Arnold Schwarzenegger, the former Mr. Olympia? In this book he co-authored with Bill Dobbins, Schwarzenegger shares how bodybuilding came to be, as well as which training systems top competitors have used to build medal-winning physiques. The 800-page book also contains multiple pictures, motivating you to get a body as good as the one’s you’re seeing in print. The New Rules of LiftingBecause men and women’s bodies are very different, The New Rules of Lifting comes in two versions: The New Rules of Lifting: Six Basic Moves for Maximum Muscle (by Lou Schuler and Alwyn Cosgrove), and The New Rules of Lifting for Women: Lift Like a Man, Look Like a Goddess (by Schuler, Cosgrove, and Cassandra Forsythe). No matter which one applies to you, reading The New Rules will give you the tools you need to develop an exercise plan that provides the best results possible given your particular sex.Any good muscle building books you’ve enjoyed that should be added to the list?
