The 66-year-old actor, who has recently gone under the knife to have neck and shoulder operations, said that he could not help chucking his body around in the latest action movie, reported Contactmusic.
"Yes the doctor said ... I had my neck fused in the last one with a stunt and a broken back ... Then I had two back operations, a shoulder operation. The last one took its toll and the doctor said, 'Don't take any rough falls, let a stunt guy do it'.
"But sometimes you just have to do it and I don't know, I just threw all common sense out of the window so, yeah, there were some injuries and some tough ones in this one, but I just can't help myself," he said.
The action movie sees Stallone star alongside Bruce Willis, Arnold Schwarzenegger, Jean-Claude Van Damme and Dolph Lundgren.
