Nina Agdal Squeezing Cheeks in the Gym!

Nina Agdal is putting in the work.

The model shared a new workout video on Instagram this week, giving followers a glimpse into her fitness routine while rocking a sports bra and a pair of leggings that left very little mystery about which muscle groups she was targeting.

And judging by one particular clip, the answer is definitely glutes.

At one point in the video, Nina can be seen flexing and squeezing her butt cheeks during an exercise, which naturally became the moment that had everyone hitting the replay button.

Nina has become a regular around here thanks to her athletic lifestyle and, of course, her marriage to WWE superstar, YouTuber, boxer, podcaster, entrepreneur, and occasional professional chaos agent Logan Paul.

Seriously, we're running out of job titles for that guy.

While Logan is busy jumping off things and wrestling people, Nina seems perfectly content focusing on fitness and reminding Instagram that she's still got it, even after popping out a baby Paul.
