A book of the year for the Evening Standard and The Times.

Then he came across a picture of a nearly naked man twenty years his senior sitting on a glacier: Dutch guru Wim Hof, whose remarkable ability to control his body temperature in extreme cold has sparked a whirlwind of scientific study. Carney signed up to Hof's one-week course, not realising that it would be the start of a four-year journey to unlock his own evolutionary potential.

From hyperventilating in a dilapidated Polish farm house, to underwater weight-lifting with celebrities in California, What Doesn't Kill Us sees Carney interview athletes, trainers and scientists about the astonishing and sometimes dangerous world of body transformation. He takes part in the UK's original - and most difficult - obstacle course: Tough Guy, and completes a record-bending, 28-hour climb to the snowy peak of M...
