If you can believe it, Chris Hemsworth's second Instagram is even better than his first. The star took to the social media platform today to share an adorable snap of him working out with one of his sons, and it is so cute and so hilarious all at the same time.

In the 'gram, the actor is pictured running on a treadmill as he flexes his left arm and holds one of his 1-year-old twins—Tristan or Sasha—in his right arm. Hemsworth's face is super intense in the picture, which he captioned: "The family who trains together, stays together!" So true, so true—especially when your dad is a superhero.

Hemsworth joined Instagram on Monday and his first photo was a selfie that featured a giant snake slithering through the grass in the background.
