Even the most beautiful stars feel it, y’all. Don’t Be Tardy star Brielle Biermann got candid about her progress in the gym and body positivity on Instagram on November 14. Real Housewives of Atlanta alum Kim Zolciak‘s daughter even admitted she is “insecure” about her bod.

“I’ve been back in the gym consistently for the past few weeks and I’m already seeing a difference,” the 22-year-old gushed in her caption, adding the double heart emoji. “My weight fluctuates a lot so I’m trying really hard to get better at eating right, going to the gym and taking care of myself,” she continued alongside the mirror selfie in which she showed off her booty gains in workout gear.

Plus, she highlighted her struggles in solidarity with other women. “I’ve always been insecure about my body, I think most women are! Push yourself. Set a goal and work towards it. Make something out of these last few weeks of 2019!! Don’t wait until the new year to become a better you,” she wrote, adding a smiley face emoji. “Thank you to my trainer @abmatthews_fit for pushing me!!”

Needless to say, Brielle’s butt looked really excellent in her photo — which definitely means she’s seeing some kind of progress with her gym routine. The blonde babe also tagged fitness influencer Katya Elise Henry‘s workout app, Workouts by Katya, in the photo, so it seems as though she’s getting advice from one of the most recognized booty queens out there.

Though she’s taken to ~hard labor~ to shape herself physically this time around, that hasn’t always been the case. In fact, Brielle got lip fillers (with mama’s permish, obviously) in 2016 at just 19-years-old. Back in January, she shared a side-by-side transformation photo to school any haters who were still talking smack about the procedure. “To those who say I look better before lips,” she captioned the old pic reminiscent of the early RHOA days. “You’re a liar and this photo is PROOOOOOF [sic].”

Mom Kim, 41, was totally on board with the adjustment from the start — and that’s really all you can ask for. “I’ve heard her complain about her lips since she came out of the womb, honestly,” she said on Watch What Happens Live after the procedure. “I was like, ‘I’m going to take you to the best.’”
