Jake Paul workout video raises concerns ahead of Mike Tyson fight

Jake Paul’s fans are concerned for the YouTuber after his body looked very different in a workout video ahead of his fight with Mike Tyson.

Jake Paul raised questions about his appearance after posting a video lifting weights while shirtless recently.

The Instagram video shows the YouTuber-turned-pro boxer, who’s training for his fight against Mike Tyson on November 15, setting a new personal record by bench-pressing 500 pounds (226kg).

However, fans seemed more interested in his stomach, which was pushed out and missing a few of his tattoos as he was apparently wearing a fake belly.

“New PR, 500 pounds,” Paul said. “I am the strongest heavyweight in existence.”

He added “Strongest boxer in existence” in his caption.

“When you due bro,” his brother Logan Paul, a fellow YouTuber who wrestles for WWE and has also boxed, wrote.

“What happened to ur belly bro,” one person asked.

“[Why] his stomach so out like that?” another said.

Paul, who’s known for his trolling antics online, seemed to be doing just that, as some suggested it was a skit involving Paul lifting fake weights.

Paul’s tattoos on his stomach and side appeared to be mysteriously missing, as further proof it was probably fake.

Last month, the internet personality looked much slimmer in a video during which he was water surfing while shirtless and had more tattoos across his belly.

Paul has been training since the summer for his rescheduled fight with Tyson.

He won his cruiserweight fight against Mike Perry in July but is looking to gain weight before his heavyweight bout with Tyson. Heavyweight fights do not have a weight limit.

The 58-year-old boxing legend suffered an ulcer problem, which pushed back the date of their bout, initially set for July 20.

Paul and Tyson had a face-off on the field at AT&T Stadium before the Saints blew out the Cowboys, 44-19, in Arlington on September 15.

Before that, the fighters met for a press conference at the Javits Center as part of Fanatics Fest NYC in August.
