Trust us, you do not want to mess with Demi Lovato.

While the "Stone Cold" singer usually shows off her fierceness on stage, she stepped things up again when she flaunted her skills in the boxing ring on Instagram Friday. In a video clip, Lovato can be seen putting up her dukes in black boxing gloves, sparring with a trainer with a determined look on her face.

"Today," she captioned the video, where she rocks her hair in a half ponytail, black leggings, black boots and a matching white and black top. As Dr. Dre's "Nuthin' but a G Thang" plays in the background of the boxing gym, she kicks and punches her trainer like a pro.

This is just the latest video Demi has shared of her boxing training repertoire. Earlier this week, she also put her moves on display, posting a clip that showed her boxing barefoot in a gym with two trainers. "Not a pro but I'm having so much fun taking out all my stress and aggression in this.. Thank you @cungle185 and @jayglazer for training me and helping me kick some ass today," she wrote alongside it.

This girl kicks butt in the gym—and in life. Keep giving us that fitspo, Demi.
