"I reckon let's just take our tops off, stuff them in our backpacks, waterproof them so we've got something dry to put on the other side," says the toned survival specialist, 40.

The 26-year-old Neighbors hunk obliges, peeling his shirt off with a grunt, showing off his beloved ripped abs. The two men strap on harnesses across their chests and their waists before rappelling down the tall cliff. 

"We started together, we're going to finish together," the former Man vs. Wild host tells the eager actor. 

Feeling proud, Efron records himself sticking out his tongue and flashing a hang loose hand sign.

Running Wild with Bear Grylls kicks off Monday, July 28 on NBC with Efron. The six-episode season will feature other stars like Channing Tatum and Ben Stiller tagging along with the British adventurer for more extreme outdoor activities.
