Description

True to his passion for the Sweet Science, Dempsey wrote a book on boxing called Championship Fighting: Explosive Punching and Aggressive Defense, which was published in 1950. The book emphasizes knockout power derived from enabling fast motion from one’s heavy bodyweight. Though no longer in print, Dempsey’s book became and remains the recognized treatise in boxing and has influenced such works from Edwin Haislet and Bruce Lee.from Wikipedia.
