Why exercise alone when you can do it together?!

Britney Spears and boyfriend Sam Asghari showed off their couples workout in a new Instagram video, and it looks like the fitness trainer is doing most of the heavy lifting, with Brit Brit on his back!

The pop princess is in the best shape of her life, but a new report claims she's gotten a little too obsessed over her body ever since she started dating her buff beau.

"Britney looks amazing and she’s got her best body ever, but she’s letting her obsession with diet and fitness rule her life to an unhealthy degree. She’s so self-conscious and can’t go five seconds without talking about cleanses or weight training," a source told Radar.

"It’s as if she’s on a weird mission to constantly look picture perfect. She’s always scrutinizing her reflection in the mirror and sometimes takes 50 photos before she’ll post one to Instagram. People are happy that Britney is taking care of herself, but now it’s getting in the way of her having fun," the source added.

We say if you've got it, flaunt it girl!
