Tamra Judge is becoming a bodybuilder!

That's right, ladies and gents! The self-proclaimed "hottest housewife" of "The Real Housewives of Orange County" has been working on her fitness and transforming into a full-fledged bodybuilder.

The 48-year-old star has been taking to Instagram to show her body progress for months, as she gears up to compete in a MuscleMania bikini-body competition in Orange County on May 28. MuscleMania is a natural bodybuilding organization that hosts national competitions, and the star has been grooming herself to be in peak physical condition for the Southern California date.

Tamra has been bulking up and getting toned for the competition, while also learning another important skill -- posing. She shared a photo with the surprising caption that the training to pose on stage is actually more difficult than working out.

For fans of the show, Tamra's transition into the world of bodybuilding is not a huge surprise. The reality star opened up her gym, CUT Fitness, with husband Eddie Judge back in March 2013, and serves as a CUT fitness instructor. The fitness studio, which got its name from the acronym Cardio Unique Training, features classes ranging from Zumba to Pilates and boot camps, and it looks like Tamra has been taking advantage of the fruits of her business operation.

This comes as great news on the heels of her rough April, when Tamra and "Real Housewives" co-star Vicki Gunvalson were involved in a dangerous ATV incident that sent them both to the hospital. From the looks of it, at least Tamra has healed up quite nicely.

Aside from sharing snaps of the body sculpting, Tamra has also been busy sharing photos of her granddaughter. Yes, folks, lest we forget the newly muscled up star is also a grandma. Her son Ryan Vieth welcomed daughter Ava with former fiancée Sarah Rodriguez back in February 2015. Though Ryan and Sarah have had a tumultuous relationship, and since broken up, Tamra remains close to her son's baby mama, and has a great relationship with her first grandchild.
