This 'Marriage Boot Camp' Drill Has Amber Portwood SCREAMING In Fear

So scary!

In a clip for Marriage Boot Camp Reality Stars: Family Edition, Amber Portwood, her mother Tonya, and her ex-fiance, Matt Baier, are put through what seems to be the scariest exercise ever! The MTV stars and their WE TV co-stars are seen sitting outside all bundled up listening to their instructions.

"No family member is allowed to remove their arm from the log until each person is holding a piece of a key," Dr. V tells the cast. Amber replies, "Dude, I'm not, I can't!" The MTV star receives some words of encouragement from Matt, who says, 'You've been to prison, you could do this."

Watch the terrifying clip above! Marriage Boot Camp Reality Stars: Family Edition airs Friday nights at 9pm ET, only on WE TV!
