Kai Trump is fueling her golf game with a protein-packed diet, clean meals and a disciplined fitness routine. She said her mother, Vanessa Trump, who is in "great shape," helped instill the healthy habits that Kai follows today. Don Trump Jr.'s oldest child said her healthy lifestyle paid off after wrist surgery temporarily sidelined her from golf. Rather than viewing the recovery as downtime, she told friends that she planned to use the time to achieve "six-pack" abs. "I literally told them, ‘I have seven months before I return to golf, we're getting a six-pack,’" she said.
