ET got an inside look at the final Dancing With the Stars rehearsals for this season's crop of ballroom warriors.

Ginger Zee, Nyle DiMarco and Paige VanZant will go toe to toe next week for the coveted mirror ball trophy in what is sizing up to be the closest matchup in DWTS history.

"It's do or die," DiMarco's pro partner Peta Murgatroyd told ET.

All three of the professional dancing partners have won on previous seasons of DWTS and the average scores for each of the dancing teams are extremely close -- VanZant and Mark Ballas average 26.4, DiMarco and Murgatroyd average 25.9, and Zee and Val Chmerkovskiy average 25.6. Knowing this, DiMarco and Murgatroyd are pulling out all the stops.

For their freestyle dance, DiMarco and Murgatroyd chose Simon & Garfunkel's "The Sound of Silence."

"Obviously I can't hear, so I think we're going to bring that out for our freestyle dance," DiMarco told ET through a translator.

Likewise, Zee and Chmerkovskiy will also play to their niche.

"Paige does somersaults and flips," Chmerkovskiy said. "I think what's been our charm is our charisma."

"When we're done with that dance, I want to look at Val and I want him to be beaming," Zee told ET. "I want him to be so proud and so happy."

The frontrunners -- VanZant and Ballas -- will be gliding across the floor to "Somewhere Over the Rainbow," a song Ballas told ET immediately felt right.

"For me, what's really special is Mark really picked this dance to format it around me," VanZant said.

The Dancing With the Stars two-night season 22 finale begins Monday at 8 p.m. ET/PT on ABC.
