Fit at 51! Jennifer Garner flexes her muscles and parades her toned figure during intense run with friend through her Brentwood neighborhood

Jennifer Garner showed off one of the the tool that has helped her keep her fab figure over the years.

On Sunday the Hollywood leading lady was spotted while out on an intense run with one of her gal pals in the Brentwood neighborhood of Los Angeles, which isn’t far from where she lives with her three children.

The former Alias star would also flaunt her fit physique in skin-tight black leggings and a matching tank top that also hugged her upper body.

She also donned a pair of black running sneakers, dark sunglasses and had her long dark brown locks pulled up into a bun, as the temperature soared up to 95 degrees Fahrenheit

Just in case she was in need of a cover-up, the Houston, Texas native tied a plaid red and black shirt around her waist, as she and her friend made their way around the suburban streets.

Taking notice of the admiring photographer, Garner, 51, gave a quick glance and smile, all while never breaking her fast pace and stride.

Her lady friend followed close behind, as the duo ran along sidewalks, through a park, and on trails, despite the scorching heat.

At times, the Dallas Buyers Club star kept up a consistent pace with her running, but then there were moments when she did some sprints, which is the best way to keep up a solid cardio program.

Garner just finished up shooting the upcoming film, Family, Leave alongside Ed Helms, which is being directed by Joseph McGinty Nichol, aka McG, from a script by Victoria Strouse with current revisions by Chris Shafer and Paul Vicknair, according to Variety.

Based on the book Bedtime For Mommy by Amy Krouse-Rosenthal, Family Leave follows Jess (Garner) and Bill Walker (Helms), who are doing their best to keep their family connected as their children grow older, more independent and more distant. 

When a chance encounter with an astrological reader causes the family to wake up to a full body switch, on the morning of the most important day of each of their lives, the Walkers must unite to land a promotion, college interview, record deal and soccer tryout. 

The cast also includes Rita Moreno, Matthias Schweighöfer, Bashir Salahuddin, Ilia Isorelýs Paulino, Fortune Feimster, Xosha Roquemore, Paul Scheer, King Bach aka Andrew Bachelor, Pete Holmes, Naomi Ekperigin, Dan Finnerty, Cyrus Arnold and Vanessa Carrasco.

This will mark Garner’s fourth major title for Netflix following her voice role in Llama Llama, Yes Day, and 2022’s The Adam Project, where she starred alongside Ryan Reynolds and Mark Ruffalo, according to What’s On Netflix.
