Kaley Cuoco's little sister's workout body is straight-up insane. The 31-year-old actress, set to feature alongside her "Big Bang Theory" alum sister Kaley in upcoming HBO Max series "The Flight Attendant," updated her Instagram this week with a power sweat session – and she wasn't messing around. Briana, who runs her Cult LA athleisurewear line, is a known workout queen, with her training coming from her current NYC location. Together with 34-year-old Kaley, Briana is in the Big Apple for a two-month shooting stint. Check out the video below.

Scroll for the video. It comes as Briana's profile shoots up with "The Flight Attendant" shooting. The brunette is also filling media outlets as paparazzi snaps of her and sister Kaley show her enjoying Manhattan – she recently shopped at popular Alo Yoga clothing brand.

The videos came with power energy and a skimpy wardrobe. Briana was seen doing burpees and a series of indoor cardio exercises working her ripped body, with a black and skintight pair of leggings and matching crop top showing the muscles off.

Bri, who featured in a 2013 episode of "Big Bang" and on popular competition series "The Voice," has also been featuring on Kaley's wildly popular Instagram series "A Cup of Cuoco." The impromptu videos show Kaley enjoying her first coffee of the day while sharing her random thoughts. A recent episode, coming from the sisters' 14-day mandatory quarantine in upstate New York, offered an exciting update.

"The Flight Attendant" had filmed six out of eight episodes prior to the pandemic pause. The series, based on the book bearing the same name, will see Kaley play Cassandra Bowden, a woman who wakes up hungover in a Dubai hotel room only to find a dead body next to her.

In August, Kaley appeared on an episode of "A Cup of Cuoco" to state that fans can expect a November airing for the series that brings her flexing her acting muscles and her executive producer ones.

Briana might not have Kaley's 6.1 million-strong following, but the star has her fans. And her updates have been getting noticed. Earlier this month, Bri updated in a cute and leggy floral-print minidress while rocking a black face mask. A caption shouted out COVID as Briana wrote: "?? w the chicest accessory of the season!! ???."

Kaley, meanwhile, has been making masked headlines for interesting reasons. A video of the star jumping rope for 100 seconds straight recently saw her slammed for wearing a mask indoors.
