For a long time, the Rambo franchise was up in the air. With a rumored continuation then a TV show that never happened, the character has been dormant for ten years. Now that we know Stallone is coming back to play the character for a fifth and most likely last time, he's teased a workout video on Instagram as he preps to blow people to hell with exploding arrows. Check out the short vid below and follow Stallone on Instagram. We're sure he'll be putting out more stuff like this as the movie ramps up. He looks like he's in damn good shape for 72 years old.
