May 4 (UPI) -- Britney Spears and Sam Asghari perform an intense couples workout in a new video.
Spears, 36, shared a compilation video Thursday on Instagram of her grueling exercise routine with the 24-year-old fitness model.
The video shows Spears and Asghari completing several paired moves, including pushups with the singer in plank on Asghari's back. The couple share kisses as Spears holds Asghari's feet during sit-ups.
"Stronger together @samasghari," Spears captioned the post.
Spears gushed about Asghari in an Instagram post in February following their one-year anniversary as a couple.
"I've been with this man for over a year... everyday he inspires me to be a better person and that makes me feel like the luckiest girl in the world!!" she said at the time.
Spears and Asghari met on the set of the singer's "Slumber Party" music video, which debuted in November 2016. Spears told Fast in the Morning in January 2017 that she hit it off with Asghari during filming.
"We started talking about sushi and started talking about things we like, and we're like, 'We should go to sushi one day!'" the star recalled.
"I kept his number and it was so weird because it was, like, five months later, I found his number in my bag. I was like, 'He is really cute. This guy was really cute.' So I called him," she said.
