Bow Diddley (Episode 9, "Still Throwin' Punches")
This grueling challenge was first seen on Survivor: South Pacific (Season 23), where it ended in a win for Savaii tribe member Whitney Duncan.
The balance beam that the castaways stand on is known as the "Cramp Ramp," a name conceptualized by the crew's head grip Callum.
To add a new twist to this season's version of the challenge, the track was made a little thinner to test the group's balance even more.
Watch the castaways compete in "Bow Diddley" in Episode 9, Season 33 of Survivor: Millennials Vs. Gen X.
