Sinner lengthens training sessions ahead of Wimbledon title defense

Jannik Sinner said he lengthened his training sessions after feeling ill and dizzy during a second-round loss at the French Open. He described the new routine as longer blocks of work in the gym and on the court without breaks. Sinner spoke at Wimbledon on Saturday while preparing to defend his singles title.

He opens against Miomir Kecmanovic on Centre Court on Monday, when temperatures are forecast to reach 77 degrees.

Changes after Paris exit After the loss in Paris, Sinner took a week off and underwent general health tests. All results came back normal, he said. He noted past struggles with heat and cramps and said the team will now practice in hotter conditions. "We need to practice in hotter conditions," Sinner said. "Every year is getting warmer and warmer."

He said playing beforehand can create doubts if results are poor, while arriving without recent matches removes that pressure. Last year he lost in the second round at Halle yet reached the Wimbledon final and defeated Carlos Alcaraz. He said the absence of recent matches left him feeling well prepared.

Membership perk As defending champion, Sinner received lifetime membership at the All England Club. He called the tournament the most prestigious on the tour and said the membership is a lasting benefit. Sinner, who is 24, added that he may not fully appreciate the membership until after his playing career ends.
