Jake Paul is pulling out all the stops in his preparation for his highly-anticipated fight against boxing legend Mike Tyson, and his latest training technique has left fans baffled. The YouTuber-turned-boxer was recently seen strengthening his hands using a bucket of rice—a method that may seem strange, but is rooted in old-school boxing tradition.

Paul, who boasts a 10-1 boxing record, has turned to this unconventional hand exercise to build muscle strength and improve his grip as he prepares for his November 15 showdown with Tyson in Texas. The fight has already stirred up controversy, largely due to the 31-year age gap between the two fighters. While Paul is just 27 years old, Tyson, at 58, is making a return to the ring nearly two decades after retiring in 2005.

Despite Tyson’s age and the health challenges he’s faced over the years, including a stomach ulcer that forced him to pull out of the original fight date in July, the boxing icon has been medically cleared to fight. He has undergone additional heart and brain exams to ensure he’s fit for the ring. This bout will be a professionally-sanctioned match, with both fighters subject to drug testing.

Jake Paul’s training has clearly caught the attention of fans and even wrestling icon Hulk Hogan, who voiced his concerns after seeing Paul in action. In a conversation with Jake’s brother, Logan Paul, Hogan expressed fear for his close friend Mike Tyson. “Your brother’s too strong, bro,” Hogan said. “He kept throwing that overhand right, and I thought, ‘Oh my God, he’s going to kill somebody.’ I love Mike, but I don’t want him to get hurt.”

The fight has already drawn immense attention, especially since it marks Netflix’s debut into live boxing events. As the showdown approaches, all eyes are on both fighters—Paul, with his rising reputation in the boxing world, and Tyson, a former heavyweight champion returning for one last professionally-sanctioned match.

Will Jake Paul’s bizarre rice training give him the edge he needs to face off against a legend like Tyson? Fans are eager to find out when these two titans collide in what promises to be one of the most talked-about boxing events of the year.
