Yasss girl! Real Houswives of New Jersey star Teresa Giudice has been looking great on Instagram recently, and judging by all of her workout videos, she's been hitting the gym super hard over the past few months and now fans know why. Teresa was training for her first-ever body building competition and she just competed Saturday, June 9 in the NPC South Jersey Bodybuilding Championships where she came in third place.

Teresa's trainer Tara Zito took to Instagram to congratulate her for her big accomplishment. "Show time Saturday! So proud of [Teresa] for stepping on stage today for her first time ever in the bikini division! Looks like she is going to take home a top [three] placing," Tara wrote.

Fans flooded the comments gushing over how great Teresa looked in her competition photos. "Teresa you look AMAZING!!" one fan wrote, while another commented, "She looks absolutely incredible!!! Shut it down [Teresa] stong mom!"

Strong mom is right! Teresa is a mommy to four daughters and even though she's always had an enviable figure, she's really had to work hard to get her body competition ready. "Teresa has been training since December and doing it five to six times a week," a source revealed to E! News. "She's also drastically changed her diet. She was looking for a new way to challenge herself and now she's in the best shape of her life."

Teresa also had a lot of support from her friends and family as she achieved her personal goal. Her brother Joe Gorga and his wife Melissa were in the crowd cheering Teresa on, and so was Teresa's pal Dolores Catania and her ex-husband Frank.

The reality star has been open about what sparked her fitness journey in the past, and she said she fell in love with fitness when she started taking yoga classes in order to keep her mind off of missing her daughters while she was serving 11 months in prison. "Yoga helped me get through it all," Teresa told Women's Health. "I used to think about them constantly. It used to break my heart, being away from them."
