Jannik Sinner has ramped up his training ahead of his Wimbledon title defense. He spoke on Saturday about changing his physical workload after his French Open meltdown.

What happened at the French Open?

Jannik Sinner felt ill and dizzy in a second-round loss at the French Open. He led 5-1 in the third set but was beaten by Juan Manuel Cerundolo 3-6, 2-6, 7-5, 6-1, 6-1.

He took a week off after the loss and did some testing to ensure his body was okay. Sinner said all tests were really good.

How is Jannik Sinner preparing for Wimbledon?

Jannik Sinner has increased his training sessions, both in the gym and on the court. He said they did everything together without any breaks.

Sinner opens against Miomir Kecmanovic on Centre Court on Monday. The temperature is expected to be 25 C (77 F) on Monday.

What are Jannik Sinner's chances at Wimbledon?

With Carlos Alcaraz sidelined due to a wrist injury, Jannik Sinner is the leading favorite to win at the grass-court major. Sinner has struggled with heat and cramps in the past.

He said they need to practice in hotter conditions, as every year is getting warmer and warmer. Sinner feels well prepared for the tournament.

Benefits of being Wimbledon champion

As a Wimbledon champion, Jannik Sinner gets an All England Club membership. He said it's a great honor for him and the most prestigious tournament.

Sinner is just 24 years old, so he probably won't appreciate the membership until after he retires from playing. He reminded that Wimbledon is the best tournament and he's happy to have this membership for his whole life.
