Ever since we caught a glimpse of Jennifer Garner's insanely toned arms earlier this year, we've been dying to know more about how the actress stays so sculpted. Well, today's our lucky day: Garner just shared a detailed look into the workout routine that got her physically ready for her new movie, Peppermint.

The mum of three works closely with celeb-favourite trainer Simone De La Rue. In a video posted to Instagram, Garner can be seen working out with De La Rue, performing a series of exercises including resistance band work, pushups, and free weights.

"In case you're interested in this kind of thing, here's a little taste of Simone and me doing what we do-basically, this is a #PeppermintMovie workout," Garner wrote in her post.

De La Rue has worked with countless celebs, including Taylor Swift, Sandra Bullock, and Reese Witherspoon. Her approach involves a combination of high-intensity dance cardio with strength training using body weight and resistance moves. Garner also turns to the trainer's Body By Simone app for custom workouts and training when she can't make it to the gym, De La Rue previously told Women's Health.

Most of us won't be training for an action movie anytime soon, but there's still inspiration to be found in Garner's dedication to being as strong and toned as possible. Can we get an invite to their next workout sesh?
