Legends of Tomorrow (2016-2021)

This CW series follows the likes of Flash and Arrow as our witty protagonist Rip Hunter (Arthur Darvill) goes backwards (and forwards and sideways) through time in order to stop an evil dictator named Savage from conquering the planet and starting the apocalypse. If you've seen either of its sister shows, you'll be pretty familiar with the characters—but this time, we get to see a bevy of them shirtless. Arthur Darvill and Nick Gracer have a showdown in a bathhouse, fighting in nothing but their towels, and both Brandon Routh and Dominic Purcell gave us a glimpse of their taut torsos, too. Aren't you glad that nudity is timeless?
