Talk about girl power — Ariel Winter is building serious muscle.
The Modern Family star shared videos from her workout on Tuesday, which included plenty of glute-boosting moves.
“Back to the gym with @mackfit,” Winter, 19, captioned a video of her deadlift exercises, and added a skull emoji.
She shared two more videos from her workout on Instagram Stories, including a set of crossover squats on top of a workout bench, and sliding lunges.
The teen actress frequently hits the gym with celebrity trainer Mack, and previously shared a video of their workout together, a series of butt-pumping leg raises — that Winter cheekily captioned with the peach emoji.

“If you want to wear a short skirt and show your body like I do, it doesn’t mean you’re a whore. And it doesn’t mean you’re not one,” Winter said in September. “People call me stupid because I post photos of my butt when the real thing is, I love my butt. I love butts! Why stifle yourself because other people can’t handle it?”
