Limitless (2011)

Limitless is a documentary series that follows Chris Hemsworth as he subjects his body to a battery of extreme physical tests, all in pursuit of longevity and peak human performance. The premise practically guarantees shirtless footage, and the show delivers plenty of it as Hemsworth strips down mid-challenge to show exactly what that training regimen produces. Brothers Liam and Luke Hemsworth join in along the way, turning the series into something of a family showcase of good genetics and hard work. Three scenes make up the collection here, less about explicit content and more about watching a trio of famously built men push themselves shirtless on camera, which is more than enough for most who tune in.
