Chiaki Tone was in Florida for about two weeks working out with Scott Mathieson. He returned on December 17, 2016. The two worked out almost every day for around five hours, beginning at 5:15am in the morning. As part of his training, he ate meals that were over 2000 kcals (included deer they hunted and alligator meat) and swam in a river with manatees.
This marked the second year in a row that Tone worked out with Mathieson in the United States.
