NEW from BILL HAYES

In Sweat, Bill Hayes runs, jogs, swims, spins, walks, bikes, boxes, lifts, sweats, and downward-dogs his way through the origins of different forms of exercise, chronicling how they have evolved over time, dissecting the dynamics of human movement. Now available in paperback.

“I was riveted by Sweat and its extraordinary tale of the ups and downs of exercise over millennia. Who knew?”

— Jane Fonda
