What does it take to get genuinely strong, healthy, and creatively alive in your late 50s — while having one of the most demanding jobs in Hollywood?

Brian Koppelman is the writer behind Rounders, Ocean’s 13, and the seven-season hit show Billions. He also helped discover and promote the singer songwriter Tracy Chapman. At 57, he walked off a tennis court mid-match, certain he was about to faint, and decided to completely rebuild his body. Three years later he’s deadlifting 300 pounds, racing up seven flights of stairs with a weighted pack, and producing some of the sharpest creative work of his career.
