The 21-year-old model spoke to Good Morning America about how he maintains his super sexy stomach.
"I try to go to the gym at least five times a week. Make it a part of my daily routine, like getting up and showering... but you have to finish your workout with a good meal," said the part-time personal trainer who sticks to a clean diet of natural foods such as chicken, fish and veggies.
The commercial in question was shot by renowned New York photographer Steven Klein and features a series of black and white images in which the model flexes an array of sharply defined muscles. Definitely an attention grabber!
Apparently Matt did not see the final cut of the 30-second ad until it aired to more than 100 million viewers earlier this week during the Baltimore Ravens v San Francisco 49ers NFL match.
"It was pretty epic.. I couldn’t stop smiling, my jaw dropped. Literally, my phone would not stop going off," he explained.
After his mother submitted his photos to a model search in 2011, he quickly became a regular working model and was recruited by fashion giant Calvin Klein last February.
Oh and girls, Matt also mentioned that he is still single and is into blondes.
