He looks absolutely fantastic.

Teen Mom OG Tyler Baltierra has come a long way in six months. The reality star has taken to Instagram to show off his weight loss, after a half year of working out and sticking to a good diet. He said on IG: "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, he wrote on the picture: "Finally getting my abs back." It was just back in February that Tyler revealed he was trying to lose weight and be healthier, by sharing two photos of himself side by side. He said: "Today marks 8 weeks from when I made the decision to make a lifestyle change. I started caring more about what kind of food I put in my body & most of all, I wanted to challenge & prove to myself that I can do it! "Today I’m 35lbs down & It has ALSO been 2 years & 26 days since I QUIT SMOKING CIGARETTES & I feel FANTASTIC! I’m crushing these personal goals & loving the rewards that come with it!" The hard work is definitely paying off.
