The Rock has been trying alternate therapies to treat his famous rippled physique.
Taking to this Instagram account on Tuesday, the retired wrestler, 48, posted a picture of painful-looking scars down his back after trying out cupping.
Cupping is an ancient alternative therapy in which a person gets suction cups put on their skin to help with pain, inflammation, blood flow, relaxation and well-being, or just as a deep-tissue massage.
And The Rock, whose real name is Dwayne Johnson, seemed impressed with the treatment, despite it leaving him with over a dozen sore patches of red skin down his back.
In the snap, he donned nothing but a white towel and pulled a shocked face.
"First time cupper over here," he captioned the photo alongside a raised hand emoji.
"Looks more gnarly than it feels, but over all I enjoyed the therapy.
"Always looking for new techniques to keep this 250million year old dinosaur body balanced and optimal with not only all my past injuries but my daily grinding family/work/training/repeat schedule.
"It all takes it toll, so being proactive is critical.
"We only get one body, so we gotta take care of it."
His followers were baffled by the post, with one commenting: "Oh my gosh that's crazy."
Another posted: "Just LOLing imagining the technician who figured out they were cupping Dwayne Johnson for work today."
While another fan cheekily compared his back to "pepperoni pizza".
