A.J. Jacobs

In his past writings, A.J. Jacobs has looked toward expanding his mind (The Know-It-All) and purifying his soul (The Year of Living Biblically); in Drop Dead Healthy, he turns toward transforming his body. With his typical level of intense commitment, the writer and Esquire editor-at-large tries every health fad presented to him—from squatting on the toilet to the treadmill desk—and reports back from the frontiers of fitness with enthusiasm.
