Former Australian politician Bob Cheek was sixty-five and running a loss-making business when he launched a chain of 24-hour gyms. Eight years and thirty-seven gyms later, he sold out for more than $50 million. Just how he achieved this remarkable feat – without borrowing any money and at an age when most people are well and truly retired – is a tale of fate, perseverance and tenacity. In Dumbbells to Diamonds, Cheek takes us through his top business 'workouts' and tells how anyone can achieve the same result with luck, timing and common-sense.
