I have quite a collection; One I recommend is Essentials of Strength and Condititioning Essentials of Strength Training and Conditioning - 3rd Edition: National Strength and Conditioning Association: 9780736058032: Amazon.com: Books
Or Exercise Physiology 7th Ed. Exercise Physiology: Nutrition, Energy, and Human Performance by William D McArdle, Bs, M.Ed, PhD, Frank L Katch, Victor L Katch - New, Rare & Used Books Online at Alibris Marketplace : this one is some comprehensive but definitely fo people experienced with the terminology
And Physiology of Sport and Exercise 5th Ed. Physiology of Sport and Exercise With Web Study Guide-5th Edition: W. Larry Kenney, Jack Wilmore, David Costill: 9780736094092: Amazon.com: Books
These 3 are all textbooks but have provided the basework for all my studies. They are however quite pricey.
I don't any 'reading' books; all mine are heavily science based.
