Serena Williams and Coco Gauff have been taking part in the well known Mouratoglou Pre-Season Training Camp and a legendary boxer has been helping to get them in shape for the new 2020 season.
That is Mike Tyson who put Williams and Gauff through their paces; on the punch bag this past week.
The American duo will both begin their season at the ASB Classic in Auckland; after the Christmas break so this is the ideal time for both to step up their preparations.
