During his appearance on Ellen DeGeneres' show, the host gave audiences a sneak peek at America's Got Talent judge's Magic Mike "cameo," in which he dances shirtless with some other nearly-naked men.
Actually, as Mandel is quick to point out, it's just footage from a particularly revealing episode of AGT, but Ellen does compliment the 59-year-old comic on his physique.
"I am in great shape. I'm in phenomenal shape," Mandel said. "I have a Jane Fonda tape. I have On Golden Pond. I work out to that, and that movie's an hour and a half."
Mandel also credits his fit figure to "running on a treadmill."
"I don't turn it on so it's a short run just from the end of the treadmill right to the front," Mandel added. "And then if I have any more energy I'll do a width. I'll do a width back and forth twice."
Check out the video for more from Mandel on his health habits, and his history of terrible dancing. His full Ellen interview airs Friday, June 5.
