Scrawny to Brawny- Michael Mejia, C.S.C.S, John Berardi, Ph.D, C.S.C.S

The definitive book for naturally skinny guys ("hardgainers") trying to put on some muscle. Scientific but delivered in simple terms. Includes of all of the background info (Why it is harder more some people to gain weight than others, etc.) Half of the book is dedicated to exercise (lifting, cardio, etc.) with a specific focus on how some lifting technique might differ for skinnier or "lankier" builds. The latter half is dedicated to nutrition/supplementation, all with an emphasis on weight gain. However, one could easily apply the nutritional lessons of this book to goals outside of weight gain.
