Teresa Giudice flaunted her taut tummy and toned arms for the judges of the NPC South Jersey Bodybuilding Championships on Saturday.

The competition, which was held in Medford, New Jersey, welcomed bodybuilders from all over the area.

The “Real Housewives of New Jersey” star, 46, took to the stage in the swimsuit competition wearing a glittery purple bikini that highlighted all of her training from the last several months.

She completed her ensemble with chandelier earrings and Lucite heels.

“She has been training since December five or six times per week,” a source told Page Six, adding that the reality TV fixture has “drastically” changed her diet.

“[She] has told friends she would consider competing in the future, but for now, no plans to do so,” the insider added. “[She] wanted to challenge herself physically and is extremely happy with how she did, coming in third out of eight.”

Fitness has been an important part of Giudice’s life since exiting prison in 2015 after spending 15 months behind bars for mail, wire and bankruptcy fraud.

In 2016, she worked to become a yoga instructor, and in her memoir, “Turning the Tables: From Housewife to Inmate and Back Again,” she revealed plans to release a yoga DVD and launch her own line.

The star’s also been relatively quiet about her husband, Joe Giudice, who’s currently serving a 41-month sentence for the same crimes.

In November 2017, Joe was transferred from a New Jersey site to a facility in Allenwood, Pennsylvania.
