Demi Lovato proudly showed off the fruits of all her training in her latest mirror selfie, posted on Friday.
The 24-year-old actress shared a photo of herself showing off her cleavage and slim torso as she wore a black bra and high-waist leggings.
She had her tresses scraped up into a high ponytail and sported a pair of gloves.
The star has been really pushing herself at the gym, and all of her exercises are really paying off when it comes to keeping herself fit and strong.
'I feel the most confident when I'm in the gym; whenever I'm training - whether it's boxing, kickboxing, Muay Thai, jiu-jitsu,' she recently told Us Weekly.
Demi has also previously made no secret of her inner demons, which included a past battle with an eating disorder.
Speaking with Fitness about overcoming her body image struggles, she told the magazine in 2014: 'I've learned to appreciate my body for what it is. It helps to remind myself how far I've come.
'I recently saw pictures from my first tour, and I spent that whole summer performing in the heat in a red leather jacket because I was ashamed to show my arms. And that was when I was 105 pounds!
'This tour, I've had the confidence to show my arms at every single concert. It may seem like a small thing, but for me, that's huge.'
