Chris Hemsworth has posted video clips of his sons having the best time ever on their dirt bikes, showing off their best moves.<\/p>\n
The Thor actor, 40, was joined by his younger brother Liam, 33, as they watched his boys drive around excitedly on the grass.<\/p>\n
Twins Sasha and Tristan, nine, were all kitted up in the appropriate protective gear including helmets, padded gloves and boots as they tried out some pretty daring stunts \u2013 proving the apple doesn\u2019t fall far from the tree with their action hero dad.<\/p>\n
Extraction 2 star Chris filmed one of his boys warning his uncle to stay out of the way before he performed an impressive wheelie, with Liam heard exclaiming \u2018blimey!\u2019 and laughing while Chris panned the camera to his face and shouted over: \u2018That\u2019s good son, well done.\u2019<\/p>\n
He also shared a slow-motion clip of his sons performing a daring trick together, which saw one lie on the floor as the other raced up a verge and jumped over him on the bike, among other leaps on the motorised bikes.<\/p>\n
\u2018My kids sending it over the weekend! \u201cHey Liam move!! \ud83d\ude02\u00a0@liamhemsworth\u00a0Yeooooooow\ud83e\udd19,\u2019 wrote Chris, who also shares daughter India, 11, with wife Elsa Pataky, in the caption.<\/p>\n

The star, who is looking to step back from his Hollywood roles, attracted praise for his parenting in the comments, with one follower responding: \u2018I love how you parent letting boys be boys!!\u2764\ufe0f[sic]\u2019<\/p>\n
\u2018Excellent, I love to see kids doing this,\u2019 added another while someone else branded it \u2018good Aussie fun\u2019.<\/p>\n
\u2018Daredevil, like his dad. Good to see a dad not wrapping his kids in cotton wool,\u2019 chimed in someone else.<\/p>\n
Another person joked: \u2018I think we\u2019re bout [sic] the same age but do you wanna be my dad? Lol.\u2019<\/p>\n
Fellow Marvel actor Josh Brolin also shared his approval in the comments, leaving a string of flame emoji.<\/p>\n
\n<\/p>\n
However, not everyone was as convinced with the activity and its safety for his young sons.<\/p>\n
\u2018I feel like Elsa must still be on her girls\u2019 trip\u2026,\u2019 shared one fan in a pointed comment, while another asked: \u2018Does your wife watch this ???\ud83d\ude02\ud83d\ude02\ud83d\ude02\u2019<\/p>\n
<\/p>\n
\u2018Thank God the boy isn\u2019t doing anything dangerous,\u2019 wrote someone else, rather sarcastically.<\/p>\n
Chris recently sent fans swooning with another of his workout videos after turning 40 \u2013 proving age is very much just a number as he put even the fittest people to shame as he worked out with ultra-marathon sea swimmer Ross Edgley, 37.<\/p>\n
