Dennis showed her followers some of her favorite ways to workout on her Instagram stories. In them, she did a lot of strength training workouts. Dennis posted three different videos to her stories of herself doing different exercises. She is seen doing TRX, Russian twists with a weight, and pull ups. Try a chest press. "Lie on your back with your knees bent and a dumbbell in each hand. Hold your upper arms perpendicular to your body and hold your forearms perpendicular to the floor. Slowly press the weights upward until your elbows are almost straight. Be careful to avoid locking your elbows into a straight position," says the Mayo Clinic. "You'll feel tension across your upper chest. Return to the starting position slowly, being careful not to drop your elbows below the surface of the bench. Repeat."

In an episode of Southern Charm, Dennis revealed her struggles with her mental health to one of her co-stars. She revealed that she deals with depression, which caused her to struggle with her life. "See, the thing is, it had nothing to do with, like, alcohol or weed," she confessed. "It's simply, like, I fell off the grid because I deal with depression and I stopped taking, like, my meds that one week, 'cause I thought I was good. And, like, I knew everyone's immediate go-to is, 'Oh, she went to rehab! It must be that she fell off the wagon.' It sucks, because it's not even a problem, but it's, like, my label."

Dennis is open about her struggles with addiction, and is currently sober. She called out a hateful social media user on her Instagram story who asked if she was high. "I haven't been high in 4 years. Am I not allowed to have a sense of humor without you people thinking I'm high?!"

Dennis is open about her life, including her acne. While she does wear a lot of makeup and use filters on her Instagram stories, she's also not afraid to go makeup free. Dennis posted a humorous video on her Instagram stories of herself going makeup free, and zooming in on a zit. She used the Stevie Wonder song "Isn't She Lovely" in the video. 

Dennis isn't afraid to indulge in her favorite foods once in a while. She posted this photo on Instagram of herself enjoying a large plate of truffle fries at the Beverly Hills Hotel. She humorously captioned the post, "When you tell everyone about your summer body goals, but didn't tell them which summer, and ask them to pass the truffle fries."
