Dwayne ‘The Rock’ Johnson has explained the reason why he urinates in water bottles while he pumps iron in the gym.

The Jumanji actor first mentioned this habit in a 2017 Instagram video, but it wasn’t until a recent Esquire interview that he went into detail about it.

“It’s not a water bottle that I’ve actually purchased solely for water that you wash and clean when you’re done using it. These are just bottles that I’m no longer using,” Johnson told the outlet.

He said that he does it because the gyms he works out in don’t have bathrooms.

“They’re just hot, sweaty and dirty.”

He explained that as a result, he “breaks out the bottle,” admitting that he has to go to the bathroom often because he stays “pretty hydrated” during the day.

Johnson also addressed rumors that his “legendary” cheat meals, which he documents on social media, are merely for show.

“I do really have cheat days. They’re not just for Instagram... I’m pretty disciplined throughout the week in terms of my working out, in terms of my diet and, when Sunday rolls around, it’s time to go to town.”

Johnson, a fitness enthusiast, has increased his exercise routine this year in preparation for the superhero film Black Adam set for release in 2022.

Johnson also has a role in the Netflix action comedy Red Notice, which debuted on Friday.

He even marketed the film by creating a billboard poking fun at his co-star Ryan Reynolds’ supposed streaming habits.
