The former “Bachelorette” star is set to compete in the upcoming season of  “Dancing with the Stars,” and has been working hard to prepare for the show, as she told her Instagram followers on Sunday.

In her post, Bristowe, 35, shared three side-by-side photos of herself to show off her increasingly fit figure.

“I’ve been working so hard on my mental and physical health over the last 14 weeks,” the reality star said. “Reading, meditating, resting, working out, lifting heavy, Pilates, boxing, going to physical therapy for mobility and strength, getting sports massages, dry needling. My body at 35 feels strong and ready to dance.”

Bristowe said she’s hoping to not be eliminated from “DWTS” on the first night after putting in so much work.

“I’m glad I have had the motivation to work towards something,” she continued. “I always think of myself as a hard worker, who also plays hard, and I’m just ready for this next chapter!!! You guys know I never post body pics but I’m proud.”

A handful of Bristowe’s famous pals offered support in the comments.

Season 4 runner-up Joey Fatone was among the stars to chime in.

“Put some clothes on!” he said, adding a winking face. “Good luck on Dwts kicks a– and if u have any questions let me know!”

“GONNA WIN,” wrote country star Carly Pearce.

“Sweat equity pays off! Keep killing it!” said fellow  “Bachelor” alum Tyler Cameron.

“You KNOW I’m be voting…and hopefully watching in person!!!” said Trista Sutter. “And ps…holy hotness!!!!”

Last season’s winner and former “Bachelorette” Hannah Brown also commented.

“Dang girl!! You look amazing!!” she said. “So excited for you!”
