Teen Mom’s Tyler Baltierra hits the gym in just sweatpants and muscle tank as fans praise his ‘sexy glow up...

TEEN Mom viewers are clearly keen on Tyler Baltierra's increasingly gym-honed physique.

The 33-year-old posted a video on Instagram of him looking buff, in black sweatpants and black muscle tank, while making a pre-workout protein shake.

The reel then cuts to Tyler pumping iron in the gym, and some of his 3.2 million Instagram followers have praised the results of his workout sessions.

One Teen Mom fan says, "You grew up and says YES GLOW UP," while another simply states, "Handsome".

Other comments include, "Tyler is one sexy man" and "Gorgeous".

Someone then even suggests Tyler is now starting to resemble a professional bodybuilder, asking him, "Have you ever thought about competing in men physique?"

It's unusual for Tyler's fans to be praising his muscular appearance, as it's normally another part of his anatomy that gets commented on.

Earlier this month, he posted a video making eggs for breakfast, but it wasn't the contents of his frying pan that fans noticed, more the contents inside his basketball shorts.

Tyler captioned the video, "I keep losing count whenever I try to add up all my blessings. I’m not mad about it!"

To which one fan said, "The snake in the pants".

And another posted, "Nobody else gonna mention it? Congrats girl".

While a third fan, jokingly added, "I'm gonna buy you underwear for your birthday, drop the addy".

MTV personality Tyler charged a monthly fee of $30 for people to get NSFW photos and videos of him on OnlyFans before recently disabling the account.

His wife Catelynn Lowell, 32, was responsible for running his account on the adult-sharing platform.

In 2022 Tyler told fans he was serious about changing his body shape and showed pictures two months apart to demonstrate his body transformation.

Speaking at the time, he spoke about his body struggles and revealed what he was doing to change things.

He said, "My whole life I hated my-ectomorph body. I've always been known as 'the scrawny dude' & I could never gain weight.

"I wouldn't even take my shirt off because I always thought I looked sickly skinny & I hated my bony chest so much that I used to swim with my shirt on lol

"So I may not be where I want to be yet (still got a lot more work to do) but I'm just trying to soak in all the little victories I notice on the way."
