He was busy working on his Hollywood star physique, but his dog wanted to be part of the fun.

Justin Theroux shared a sweet video to his Instagram Stories on Wednesday of his Pit Bull mix Kuma trying to join in as he did a series of push ups.

The 48-year-old Leftovers star didn't seem to mind the interruption from the loving pup, whom he adopted in 2018 in the aftermath of the devastating Hurricane Harvey.

Helping out: Justin Theroux, 48, shared a sweet video to his Instagram Stories on Wednesday of his Pit Bull mix Kuma trying to join in as he did a series of push ups

Justin filmed himself head-on for the Insta Stories clip as he settled in for some push ups to aid his bulging biceps.

He was dressed casually for his workout in a Britney Spears 2001 tour tank top with black Adidas track pants and black trainers, along with a charcoal ski cap.

He'd barely gotten in two reps, set to MC Serch's Back To The Grill, before Kuma leaned in to lick his face as he moved up and down.

But the gray Pit needed more affection, so the American Psycho actor stopped what he was doing to let her jump up on her hind leg for a hug and some petting.

Looking for love: Justin was dressed sportily in Adidas track pants and a Britney Spears 2001 tour tank top as he showed off his bulging biceps, but Kuma was in desperate need of attention

Affectionate: After she licked him uncontrollably, Justin paused to let her climb up on him for some kisses while he petted her backside

In the way: But even after he started again, she slid under him to force him not to squish her

Justin went back to his push ups, but now Kuma arched her back and laid underneath him so that he had to tap her on each down stroke.

The actor eventually gave up and just settled for some kisses from his loyal dog.

Kuma has been a fixture in Justin's life since 2018, when he adopted her after she was left homeless and alone in Conroe, Texas, following Hurricane Harvey.

At the time, Kuma was named Sylvia, and she suffered from multiple medical issues that caused her fur to fall out, revealing the pink skin underneath, according to The Dodo.

Her eyes were also nearly crusted shut due to mange caused by a parasite.

Heartbreaking: Justin adopted Kuma, then called Sylvia, from Texas in 2018. She was left homeless after Hurricane Harvey from August 2017, and her fur was falling out and her eyes were nearly crusted shut from mange

Fast friends: The Leftovers star adopted her while in Texas after seeing an online ad about the newly healthy Pit Bull mix in need of a home. He renamed her Kuma, meaning 'bear' in Japanese

But after intensive therapy and treatment for her medical issues, Sylvia's lustrous gray coat returned in full, and she put on weight and muscle.

When a notice was posted online about the Pit Bull mix in need of a forever home, the local shelter got a notice from the president of the Austin-based shelter Austin Pets Alive that a VIP client was interested in the dog.

The VIP turned out to be Justin, who was in Texas at the time and made the multi-hour drive to visit Sylvia, whom he'd rename Kuma, Japanese for 'bear.'

The two have become inseparable since then, and the actor is regularly spotted out and about with her.

Inseparable: The two are now nearly inseparable, and he's regularly spotted out on walks with her. She joined him in a February campaign to get the Denver city council to repeal a Pit Bull ban

She's also a visible symbol of his commitment to dog's and their rights, particularly Pit Bulls.

In February, Justin shared a photo of himself and Kuma sitting down for a morning coffee as he urged the Denver city council to repeal a ban on Pit Bulls.

'All they want is the right to be available for adoption from your shelter facilities, get registered, microchipped and be LEGAL... so they can be the the incredible Denver citizens that Kuma and I know they can be,' he wrote.

But Justin sounded heartbroken after the Pit Bull ban continued in Denver due to a veto from Mayor Michael Hancock.

'A special apology is in order from you @mayorhancock to all the Denver animal control workers who have the truly nightmarish job of putting these beautiful dogs down on repeat in service of your ignorant policy,' he wrote.

'Maybe skip a Broncos game and be courageous enough to attend even one of these murders at YOUR city shelter, to understand the impact of your policy.'
