"Outside but barely" - Pregnant Naomi Osaka gives behind-the-scenes look at her new tennis training regimen

Last month, four-time Grand Slam champion Naomi Osaka announced that she's expecting her first child later this year, and that she hopes to return to tennis with a new vigor in 2024.

Her commitment to that goal seemed all the more evident in a social media post that she shared on Monday.

"Outside but barely," the former World No.1 joked underneath a carousel post of recent training videos.

The collection featured two video clips of her hitting on a tennis court, and a third of her doing a low-impact fitness routine on the beach. In the second clip, Osaka can be seen training under the watchful eye of International Tennis Hall of Famer Andre Agassi.

Since announcing the impending addition to her family, Osaka has nonetheless stayed busy through a variety of off-court endeavors.

She was in the stands as a fan at Super Bowl LVII, and was one of many who raved about Rihanna's performance at halftime, and recently announced a new collaboration collection with American clothing retailer Victoria's Secret.
