Tyler Baltierra is showing that hard work makes for hard abs!

The Teen Mom OG star hit up social media to highlight what a difference six months has made.

The reality star wrote, "Hard work is paying off! It’s been 6 months since completely changing my eating habits, I dropped 40lbs & now it’s time to cut it all up with these workouts, BOOM! #CrushingThesePersonalGoals #ItFeelsGreat."

In addition to the caption, the 26-year-old, who is married to Teen Mom OG's Catelynn Baltierra, wrote, "Finally getting my abs back."

In February, Tyler revealed he'd lost 30 pounds in two months and it was due to a big change in eating habits.

"The cool thing is, I'm actually learning how to cook pretty decent now! Almost been 8 weeks since I made the decision to eat healthier & I'm down about 30lbs & I FEEL GREAT! #Motivated," Tyler tweeted. "I'm not really 'on a diet,' I just started caring more deeply about what I was putting in my body. To jumpstart the weight loss, I cut out carbs (besides toast in the a.m.), filled up on fruit, smoked fish, & vegetables for lunch & ate lean meats, vegetables & salad for dinner."
