Rob Lowe reveals how Tom Cruise's iconic run is connected to their Outsiders costar Emilio Estevez

No one in Hollywood has a more iconic running style than Tom Cruise — and one of his Outsiders costars thinks he knows the origin of the flat-palmed, straight-backed sprint.

In the latest episode of their Fly on the Wall podcast, Dana Carvey and David Spade discussed the Top Gun star with guest Rob Lowe, who was among the greaser ensemble in The Outsiders alongside Cruise, Patrick Swayze, C. Thomas Howell, Ralph Macchio, Emilio Estevez, and Matt Dillon.

"You know, Tom Cruise runs with his hands straight up and down like this for less wind resistance," Spade observed, while holding his palms flat in front of the camera.

"In case he has to karate chop somebody," Carvey joked. 

"And he usually runs for about roughly 15 to 20 minutes through every movie in a full sprint, every take," Spade said.

Carvey took the opportunity to ask Lowe about his knowledge of Cruise's physical performances. "He knows his way around the movie business, and I have a question for Rob," the comedian said. "If I ran into Tom, I'd say the most impressive thing, if it's real, is not hanging off the airplane [in Mission: Impossible]. It's sprinting with that kind of authority at 60-something, because the hip flexors — so do you think they do slightly speed it up a little bit?"

Lowe said he doesn't believe Cruise's films speed up his pace. "No," he said. "Tom and I, I could be wrong, but I think we both initially learned to run from Emilio Estevez's running coach."

The Parks and Recreation star identified the coach as the record-breaking triple-jump athlete Milan Tiff, noting that he trained Cruise and Lowe after The Outsiders. "We were all training with Milan, the hand thing was the big thing," Lowe said.

"You also make it a flap, by the way. There's this," he continued, holding up his hands with a slight curve in the extended fingers and moving them from his head to his torso. "And then you make it a little flap. Little dolphin move."

Carvey also noted that Cruise rarely disrobes on screen at this point in his career. "I love Tom Cruise," he said. "The guy's brilliant, but he doesn't take his shirt off anymore, does he, in movies?"

"No, because he's smart," Lowe said. "I took a lot of s--- [when photographed shirtless]. I said, 'Frame it correctly.' There's a certain level with which the framing reveals, you know, that I'm in my third trimester. My donut belly."
