Lupita Nyong’o is making an impression on her fans after posting a behind-the-scenes video to show the world how she trained in the water while shooting Black Panther: Wakanda Forever. The 54-second clip shows the actress, who played as the “war dog” spy Nakia, swimming underwater while carrying dumbbells, which appear to be about 10 to 15 pounds. 

“Swimming down to Talokan was not as easy as it looked! Safely supervised by @XPTLife and #MarkRobertsFitness,” Nyong’o captioned her TikTok video.

As she submerged underwater in the beginning of the clip, Nyong’o used her left hand to hold the dumbbell to her chest. At the same time, she used only her right arm to swim in a straight line.

She later bear crawls underwater carrying two dumb bells. The Black Panther star continued to dazzle her fans when she gracefully walked up the steps of the pool.

As the clip comes to an end, the 39-year-old star puts the dumbbells down and swims back to the surface.

“I feel like a crawfish,” Nyong’o wrote on the clip.

Fans are raving about the actress after seeing the footage.

“HOLY HELL, Lupita! This is beyond incredible!” one person said.

“Soooo much respect! You make it look easy,” another TikTok user wrote.

The Hollywood star also received praise for her impeccable figure and slick underwater outfit.

“THE NEW SUIT WAS SO SICK YOU DID SO GOOD SLAY,” a TikTok user said.

While Nyong’o proved herself as an elite swimmer, some of her colleagues had to learn the skill for the movie. As Blavity previously reported, director Ryan Coogler sat down for an interview with Variety earlier this month and said he had to learn how to swim when they were shooting the Black Panther sequel.

“If the camera is in the water, actors are in the water, I’ve got to be in there too,” Coogler told Variety. “I had to figure out how to swim, so I could direct this movie.”

Angela Bassett, who plays T’Challa’s mother, Queen Ramonda, also had to sharpen her skills in the water. When Coogler asked her if she can swim, Bassett said she told him “a little bit.”

“You know, Black girls have this history with water and their hair,” Bassett told Variety. “Some of us can’t swim all that well, because it’s going to mess up that press and curl. It’s a whole thing.”
