Sylvester Stallone is hitting the gym in preparation for a return to his new Rambo 5 movie.
Even at the age of 72, he still crushes it in the gym, and he has the physique of a man half his age.
Rambo 5 comes 10 years after the fourth Rambo film hit theatres back in 2008.
The movie is expected to be release in 2019.
