Written by Dr. Mel Siff, Supertraining is a classic text in the field of strength and conditioning.  Based on its reputation alone, this was one of the first books I bought on the subject and I couldn't really appreciate the quality and amount of information provided because I didn't know much about the subject.  Now having been through graduate school, I still look at this book as one that covers just about everything: basic biomechanics, physiology, energy systems, skill acquisition, all types of strength, endurance, flexibility, power, periodization, lists of exercises.....you name it. 



The beginning of the book defines strength and gets into muscle composition, biomechanics topics like mass-acceleration and muscle tension, muscle fiber types, and bioenergetics.  These were really the types of things we first covered in beginning classes for exercise science.  What it isn't is a list of programs for you to just follow along, what it is is the kind of information you need to plan for yourself or your players.

A couple of the topics I have found more interesting and applicable are information about the "feedforward process" and also differentiating types of muscle hypertrophy:




The book has traditionally been tough to find so I was glad to see a place like Perform Better pick it up.  If you're interested in reading more, another review can be found here.
