Brie Larson refuses to do conventional workouts.”

Fans of Brie Larson know that she seems to enjoy keeping things interesting when it comes to fitness. According to her Instagram account, her workout routine lately has included sweat sessions on the rowing machine, weighted push-ups, and even inverted core exercises. Now the Marvel actress is confirming her love for unexpected workouts with a new post.

“My #AntiHero trait?” she writes in her caption. “Reject conventional training.”

Her words are paired with a video of Larson pushing a weighted sled up a stone driveway. She steps one foot in front of the other on the balls of her feet. Her upper body leans forward and her arms are stretched out in front of her, her hands are on the handlebars of the sled. She's wearing matching gray and white checked leggings and a sports bra with white sneakers, and her hair is tied up in a bun.

Larson tagged Taylor Swift in her post, which was set to the singer's new hit "Anti-Hero." ICYMI, the song was part of a viral trend circulating online in which people playfully exclaim their "problematic" tendencies to the lyrics "It's me, hi, I'm the problem / It's me." (Psst: Shania Twain also recently jumped on the trend with a video of her horseback riding.)

This isn't the first time Larson has shown off her sled pushing skills on Instagram. She shared a series of pictures of her pushing a four-wheeled sleigh in June 2022. And there are many reasons why she wants to return to the exercise.

It's "a safe and effective way to increase both performance and overall conditioning," Marty Miller, DHSc, NASM Regional Master Instructor and Vice President of Education and Training at Technogym North America, previously told Shape. The exercise uses the glutes, quadriceps, hamstrings, and calves to generate enough force to push the sled forward. It also targets the core, chest, shoulders, and triceps.

Sled pushes get the heart rate up for a cardio workout that burns calories while building muscle, Sloane Davis, certified personal trainer and founder of Pancakes and Pushups, previously told Shape. Not to mention the fact that sled kicks require unilateral movements (aka one leg at a time). This is the key to building symmetrical strength in the body and improving stability.

That could be why other celebrities have reaped the benefits of sled pushing. Tracee Ellis Ross, Kate Upton, Kate Hudson and Lizzo have all recently shared clips of their own sled training sessions. It's an exercise you won't want to skip, especially if you're a fan of more unconventional sweat sessions like Larson.
