'Thor 3: Ragnarok' Cast: Chris Hemsworth Working Out With Son & Shows Off Muscles, 'Family Who Trains Together, Stays Together' [Photo]

Chris Hemsworth is getting the hang of Instagram as he posted another adorable picture in the social media website, Yahoo! TV reports.

The "Avengers: Age of Ultron" actor may be new to Instagram, but he sure knows how to put a spin of humor on his pictures. On his second post, the actor shows off his biceps while working out on a treadmill. And his favorite gym buddy? None other than one of his 19-month-old twin sons, looking very chill while being carried by his flexing dad.

Hemsworth captioned the post, "The family who trains together, stays together!" The picture has already garnered 72,300 likes, as of press time, as well as positive reactions from his followers, some commended Hemsworth body while most just typed one emoji after another.

On Monday, ET Online reports that the sexiest man alive made has finally made an Instagram and made his debut with a selfie. But this is no ordinary selfie, as the actor, who was wearing an FDNY cap, snapped a pic of him and a giant snake. He captioned the selfie, "Hangin' with the locals in my backyard… the real Jurassic Park!" Since creating his Instagram account a few days ago, Hemsworth has already 458,000 followers and has followed some of his family and friends in the industry including his "Avenger" co-stars, his brothers Luke and Liam Hemsworth, the official account of "Saturday Night Live," Ron Howard (his director in "Rush" and "In the Heart of the Sea"), and, of course, his lovely wife Elsa Pataky's fan account.

Last month, a separate ET Online article showed topless pictures of Hemsworth while the Aussie actor got stoked in Byron Bay in News South Wales, Australia, which is reportedly teeming with sharks. Armed with his surfboard, 32-year-old actor hit the waves with 50 other surfers while the public is treated with another bunch of topless pics to enjoy.

While fans are enjoying Hemsworth sexy dad pictures, a previous Parent Herald report said that his next "Thor" installment, titled "Thor: Ragnarok," will be darker than its previous installments.

According to Birth.Movies.Death, Christopher Yost's storyline was too dark that Marvel Studios had to lighten up its "apocalyptic vibe" by hiring Taika Waititi. Because of the director's comedic background, Marvel Studios hopes that Waititi's involvement in the filming process might lessen "Thor: Ragnarok's" grimness. Also, Mark Ruffalo's character, The Hulk, is reportedly joining Hemsworth on "Thor: Ragnarok" and will have a major role. The Hulk and Thor will go on a "cosmic journey" together, adding a touch of humor to the serious storyline.
