The full scene if anyone’s interested.

Carl Weathers is an interesting contrast to Arnold. Arnold got his muscles by focusing on how he looked, on bodybuilding. Weathers developed his physique training for professional gridiron football. He played college football, then in the NFL (coached by John Madden) and CFL. Arnold used his unique physique as a way to get into movies without ever training as an actor. Weathers was studying theatre arts while playing college football, and finally finished the degree in 1974 just after retiring from pro football. He went on to get a master of theatre arts later.

Both of them pivoted extremely successfully to comedy later in their careers, with Weathers doing Happy Gilmore and Arrested Development, and Arnold doing his whole variety of comedy movies.

Also, good to know that Weathers loved this scene:

“Predator, the handshake. That’s iconic,” says Weathers, grinning from ear to ear. “The director shot that scene beautifully. And it’s a great movie. You put that movie in the theater today and it works just as well as it did back in 1987.”
