Jennifer Garner flexed her buff arms while on the set of her upcoming Netflix comedy in downtown LA on Wednesday.

The four-time Emmy nominee - turning 54 next month - flashed her purple bra beneath a pink button-down tank top, green cargo pants and sneakers selected by costume supervisor Leeann Radeka.

Garner kept her make-up minimal but wore a reddish-brown wig featuring chunky blonde highlights.

In the show, One Attempt Remaining, the producer-star and retired WWE wrestler John Cena portray an 'embittered' divorced couple, who have 48 hours to remember a password in order to uncover their $35 million cryptocurrency fortune. 

It is being directed by Kay Cannon, who previously helmed Cinderella (2021) and Blockers (2018) and wrote the Pitch Perfect trilogy and its spin-off series.

Stranger Things producer Shawn Levy is also overseeing the funny flick, which stars SNL alum Kate McKinnon and Your Friends & Neighbors actress Aimee Carrero.

Garner famously got her start in the industry with stunt-heavy roles in ABC's spy thriller Alias (2001-2006) and the 2003 Marvel movie Daredevil, which introduced her to her second ex-husband, Ben Affleck.

And the amicable exes reunited on Saturday at Combat Paintball Park in Castaic, California, of all places.

Garner and the 53-year-old Oscar-winner were there to celebrate the 14th birthday of their son Samuel, one year after he was pictured embracing her as she took aim at the same paintball park.

The Texan-born, West Virginia-raised beauty and Affleck also welcomed two daughters - Violet, 20, and Fin, 17 - during their decade-long marriage, which ended in 2018 with 'two separate households.'

'I become mom and dad; he becomes dad and mom,' Garner told Bustle last week.

'You kind of can't help it, right? Because you don't have the benefit of both sides of the yin and yang being in the same house. And so you have to have a bit of both in the way that you parent.'

The Golden Globe-winner added: 'There's a little bit of loss in that, but there's also something gained in that.'

Garner executive produces and stars as woodworker Hannah Hall in the eight-episode second season of Laura Dave and Josh Singer's thriller The Last Thing He Told Me, which currently airs Fridays on Apple TV.

The Angel City FC co-owner's other upcoming projects include Netflix holiday comedy Mrs. Claus, Max Winkler's true-crime film Fruitcake and Peacock's eight-episode drama The Five-Star Weekend.

On February 6, Garner and her Once Upon a Farm co-founders, Cassandra Curtis and John Foraker, went public with their children's food company as 'OFRM' on the New York Stock Exchange.
