The photo shows Lovato wearing her jiu jitsu uniform at Unbreakable Performance in Los Angeles. She encouraged her fans to keep fighting in the caption.
"Sweaty, messy jiu jitsu hair.. #BJJ #bluebelt #nevergiveup," the star wrote.
Lovato earned her blue belt in Brazilian jiu jitsu in August 2017. She celebrated the achievement in an Instagram post at the time.
"I'm so beyond excited because I just received my blue belt in #brazilianjiujitsu!!!!" the singer told fans. "I fell in love with #BJJ over a year ago and have been training several times a week ever since."
"I have always been transparent about my journey with addiction," the star wrote. "What I've learned is that this illness is not something that disappears or fades with time. It it something I must continue to overcome and have not done yet."
"The love you have all shown me will never be forgotten and I look forward to the day where I can say I came out on the other side," she said.
