JoJo Siwa flaunted her toned body on Instagram Saturday by posting two photos, which she described as the "first and last pic of 2022."

In the first image, one can see a closeup of the reality star's sweaty forehead. The second one, on the other hand, shows the 19-year-old celebrity flaunting her abs in the bathroom mirror.

"First and last pic of 2022," Siwa wrote in the caption.

She also shared how she felt about taking progress photos, noting, "I NEVERRRR take 'progress pictures' because they make me uncomfortable... however after a year of putting tons of focus on my physical health I am soooo proud of the muscle/strength I've gained!!"

She added, "I looked like the first picture EVERYDAY literally. Sweated and sweated. HAPPY NEW YEAR EVERYONE!!!!"

The post's comments section was quickly flooded with messages from fans and fellow celebs who complimented Siwa and told her how inspiring her progress was.

YouTuber Trisha Paytas wrote, "Wow 👏 so inspiring! This is amazing 🙌 You look great!"

Meanwhile, dancer Kinley Cunningham said, "Sooo proud of you JoJo! Love you!"

An Instagram user commented, "Inspiring young girls to focus on the health/strength aspect of working out <3 that's what it's all about Jojo."

A fan also encouraged Siwa to post more progress photos.

Siwa previously disclosed that her life has changed for good ever since she came out as pansexual.

It can be recalled that she came out in January 2022 by sharing a photo of herself wearing a shirt with the text "Best. Gay. Cousin. Ever." printed on it.

"In the last 365 days I've felt more love than ever," she wrote in the caption of the picture, which she posted on Instagram. "Truthfully I feel like I was put on this earth to be a role model for kids, and letting all the kids of the world know that loving everyone for who they are no matter what is something that I will always believe in and always share."

She concluded, "Thank you for showing me the most love throughout this year and throughout my entire life."

Aside from flaunting her physical transformation and coming out as pansexual, the reality star made headlines last year for dating TikTok star Avery Cyrus for three months. Cyrus disclosed their breakup on TikTok in December.

On the work front, Siwa was last seen in the TV series "High School Musical: The Musical: The Series," appearing in the seventh episode of its third season. She was also part of the 30th season of the reality competition show "Dancing with the Stars," which premiered in September 2021 and ended in November of the same year. Siwa will be next seen in the horror movie "Sketch," which is helmed by director Colton Tran.
