Who doesn't know who Jason Momoa is?

The majority of America will agree with the fact that Jason Momoa is one of Hollywood's biggest heartthrobs.

He was born in Hawaii.

He was born in Honolulu, Hawaii, and moved to Iowa when he was growing up. He initially majored in marine biology before switching to wildlife biology, until he began a modeling and acting career in 1998.

He's most famous for his role in fantasy series, Game of Thrones.

He played the role of the Dothraki King, Kahl Drogo, who caught the interested eyes of many viewers with his macho persona and intense good looks. His 6ft 4" height was emphasized massively in this role, and we all know that the women of America are suckers for some height... well, I know I am, anyway...

Momoa has had his fair share of TV appearances...

The thirty-nine-year-old has also appeared in Stargate Atlantis (2004), Conan the Barbarian (2011), and his most recent starring role was in Aquaman (2018).

Jason is happily married with three kids.

Jason began dating actress, Lisa Bonet, in 2005. The couple were legally married in October 2017 after ten years of partnership. Through his marriage to Bonet, he became a stepfather to her daughter, Zoe Kravitz, who is famous for her role in Big Little Lies. Jason and Lisa have since had two children together, a daughter and a son, who were born in 2007 and 2008.

Like any family, the Momoas enjoy vacations every once in a while...

But the main downfall of being a celebrity is the paparazzi. Hot snaps of celebs on beaches while trying to enjoy their vacations are what makes magazines sell - it's a sad reality of journalism, my friends...

While enjoying a vacation in Italy last week with his wife...

The actor was photographed by a pool in their vacation home in Venice, prompting a surge of comments on social media.

As one would expect, a lot of comments were gushing over the Hawaiian-born actor...

Users took to Twitter to express their love for Momoa, branding him as "gorgeous," which is totally true...

But the body-shaming (somehow) soon began...

According to The Independent, users on Twitter and Instagram were leaving cruel comments such as: "where are the abs?" and the star was criticized for sporting a "dad bod."

The mind boggles...

Trust me, you aren't the only one who is baffled as to how people have the audacity to call somebody out for this...

Jason's legion of fans are having none of it...

This user acknowledged that, despite Jason's super ripped body on screen, at the end of the day, he's just a normal guy who's body isn't permanently oiled up and bulging with muscles.

People are sharing their confusion...

...  What dad bod?

The phrase has been thrown around a lot on Twitter...

But what exactly does it mean?

Apparently, it's "science..."

Twitter seems to think that the dad bod is in fact, the most attractive male body type in the eyes of women.

The dictionary definition of the dad bod...

According to the Cambridge Dictionary, a dad bod is "the body of a man who is slightly too fat and does not appear to do a lot of exercise." Okay then...

Health organizations are not happy about this label...

Men's Health UK is slamming the use of the term "dad bod," saying: "The man is thirty-nine years old, he is, in fact, a dad, and he definitely deserves a nice, long family vacation. And even if you don't like how he looks, why do you need to say anything!?"

It's not easy to train like a world-class athlete every day...

"Not to be dramatic, but choosing to hate on Jason for, I don't know, deciding to finally not train like some kind of world-class athlete seems unfair," Men's Health went on to say.

It is undeniable that Jason is in great shape...

"Dad bod" or not, the Aquaman star is still in amazing shape - having abs and bulging muscles doesn't always define perfect health. Jason's personal trainer, Mark Twight, spoke to Men's Health about the strict workout regime that prepared him for his role in Aquaman.

"Sometimes the student is also a teacher..."

Twight met Jason when he was preparing for his cameo in Batman vs. Superman, and their mutual interest in climbing started their friendship.

"During that job, Jason coaxed me into visiting Planet Rock, a Detroit-area climbing gym. I was out of shape for it, but he was patient and his enthusiasm for climbing was contagious. I hadn’t realized how I missed it or that I could climb again without it being my identity. Sometimes the student is also a teacher," Twight recalled.

A simple approach to balance weightlifting and climbing...

So what about Jason's workouts? "We took a simple approach to balance weightlifting with climbing, " Twight explained, "we didn’t fatigue the muscles used for climbing (back, biceps, and forearms) the day before hitting the rock gym. Instead, we trained back and biceps after climbing to overload them. This freed other days to focus on chest, shoulders, and legs."

I'm even tired just thinking about that...

So yeah, turns out that Jason Momoa is a pretty fit guy, if you weren't already aware.

Workouts don't have to be fun, to be fun...

"Treat the workouts as play. And make them hard. My motto from when I was climbing full-time is just as relevant here, 'it doesn’t have to be fun to be fun.,'" Twight advised.

Body issues can affect anyone...

These ignorant criticisms aimed at Momoa come days after British singer, Sam Smith, opened up about his lifelong struggles with body image. Men aren’t supposed to cry or be emotional," Smith said to Jameela Jamil as part of her body positivity series, "I Weigh Interviews," adding that a reluctance to address physical insecurities is part of the “toxic masculinity conversation."

Men should be open to discuss their bodies and insecurities just as much as women...

"It doesn’t feel manly does it, to talk about how I feel in my body every day," he added, "but that’s what I’m trying to fight against I guess."

So who cares if a man has a "dad bod" or not?

Regardless of their physique, a man should be praised for embracing his body. No one deserves to be body-shamed. Love what you've got, guys! If you're after a little more body-positivity, look no further than the incredible Serena Williams. She recently posed for the cover of Harper’s Bazaar and refused to allow her body to be edited. She looks stunning. Keep scrolling for the full story!
