查尔斯·盖恩斯于周二去世，享年84岁 [1]。这位著名作家与乔治·巴特勒合著的《健身铁血》（Pumping Iron: The Art and Sport of Bodybuilding）出版于1974年 [1]，该书最初源于他1972年为《体育画报》撰写的一篇关于美国东海岸健美赛事的文章 [1]。
《健身铁血》及其1977年改编的同名纪录片 [1] 将专业健美运动推向主流社会，并将阿诺德·施瓦辛格介绍给世界观众。施瓦辛格曾赢得7次奥林匹亚先生和5次环宇先生冠军 [1]，并在随后的职业生涯中担任加州州长，任期从2003年至2011年 [1]。
盖恩斯从16岁开始从事健美运动 [1]。他毕业于伯明翰-南方学院（学士学位）和爱荷华大学（艺术类硕士学位） [1]。除《健身铁血》外，他还著有《Waters Far and News》和小说《Stay Hungry》[1]，后者被改编为电影，由杰夫·布里吉斯主演，该片成为施瓦辛格的首部电影作品 [1]。
Charles Gaines, the writer whose book brought professional bodybuilding into mainstream culture, has died at age 84 [1]. He passed away on Tuesday [1].
Gaines co-authored "Pumping Iron: The Art and Sport of Bodybuilding," published in 1974 [1], which originated from a 1972 article he wrote for Sports Illustrated about the Mr. East Coast bodybuilding competition [1]. The book was adapted into a documentary film released in 1977 [1], introducing Arnold Schwarzenegger to global audiences [1].
Schwarzenegger, featured prominently in both the book and film, went on to win seven Mr. Olympia titles and five Mr. Universe championships [1]. He later served as Governor of California from 2003 to 2011 [1].
Gaines began his involvement with bodybuilding at age 16 [1]. He held degrees from Birmingham-Southern College and the University of Iowa, where he earned a master's degree in fine arts [1]. Beyond "Pumping Iron," his other notable works included the novel "Stay Hungry," which was adapted into a film starring Jeff Bridges and marked Schwarzenegger's first movie role [1], as well as "Waters Far and Near" [1].
