Alexis Bellino is reinventing her look one hair color, Botox tweak, and sit-up at a time. OK, so maybe she doesn't do her sit-ups only one at a time. Because, as The Real Housewives of Orange County alum recently revealed, she has some seriously toned abs.

In a February 18 Instagram post, the mom of three stood in front a mirror with her shirt pulled up to expose her bare, tanned midriff. Though she had clearly defined abs, Alexis indicated that she's just getting started on her physical transformation.

"Thanks to @jakebarrena for the training and @acbohnz for the fasting technique...the abs may be out by filming date. Working hard. Crossing fingers," she wrote. (A little context: Alexis has announced that she's in the midst of filming a new reality show.) Her caption continued, "Definitely will show before/after from Jake’s amazing training workouts." 

Wait, her abs may be out? Then what are these? 

Even though she was humble, Alexis had to admit that her lifestyle changes have been effective. Sharing that she has tried fasting 24 to 40 hours between meals, the Orange County beauty shared: "I felt great! It works!!!!!!"
