Shay Mitchell (Emily) may be injured on Pretty Little Liars — she hurt her shoulder after having a swimming accident on pain meds — but in real life, this sporty lady is literally kicking butt when it comes to exercise.

The PLL actress took to Instagram on September 11, posting a photo of herself throwing punches in a boxing ring. Along with the pic, Shay wrote, "Crazy late night boxing session with @gabejohns thanks @jeremiahlazo for the pic #pow."

Even when working up a sweat, this Little Liar is still glowing. For the late night workout, Shay rocked pink Everlast boxing gloves, a matching pink tank-top, and black and white leggings. Only the most stylish for our girl!

As for what else this pretty little boxer does to stay in shape? She's posted photos of herself taking spinning classes and has been seen going for jogs around her neighborhood. We feel healthier just looking at her!

What do you think of Shay's boxing workouts? Sound off in the comments.
