Lovato -- who frequently shares video of her workouts on social media -- is no stranger to the boxing gloves.
Last month, ET spoke to personal development coach Mike Bayer -- who founded and now co-owns the mental health facility CAST Centers with Lovato -- about how staying physical helps the singer achieve her own wellness goals.
“Trying to make yourself do something that you don’t enjoy doing just doesn’t work, so my job is to figure out a strategy," he explained. "Demi is doing Jiu-Jitsu, and she’s already got a stripe on her belt. She loves Jiu-Jitsu, and she loves kickboxing, and I create a plan around that because I knew that for her, that would be a passion. That would be enjoyable. That would make her feel accomplished."
Doing what she loves has clearly payed off for Lovato -- we wouldn't want to face off with her in a ring anytime soon!
