"I'd rather people just call me Joe, but it's not that bad," Amabile said about his nickname from his time on The Bachelorette and Bachelor in Paradise.
Amabile has no dancing experience, and Retton says that she has only had a little bit of ballet training.

You would think that Retton's amazing athletic abilities would be a huge advantage, but she says they are very different.
"In terms of the technical side of gymnastic and the technical side of dance, no, I knew nothing," Retton said.
She said that she hopes her ability to have a stage presence and perform in front of a crowd will help.

Amabile said that he doesn't think the crowds will be a problem for him because he will be too busy trying to remember all of the steps.
"Five minutes to show time, I could freak out," he admitted. "I'm sure everything is going to be a problem."
"No, no, we're going to be back there being moral support for each other," Retton said.
Retton will dance the Cha Cha with her pro partner Sasha Farber, and Amabile will be dancing the Quick Step with Jenna Johnson.
Both are looking forward to having their friends and family cheer them on. Amabile said that things are going very well with his girlfriend from Bachelor in Paradise, Kendall Long, so Bachelor Nation is hoping that she will be there to cheer him on.
