K.J. Apa, Eli Goree & Cole Sprouse on Riverdale (2019)

Episode 2 of Riverdale's new season pulled out the big guns as it featured several shirtless scenes throughout the hour. The episode began with Archie (played by K.J. Apa) doing some sparring in the boxing ring with his pal Monroe (played by Eli Goree). Both of the teens were topless for the session. Later, Monroe joined Archie on the football team, leading to some towel-clad time in the locker room for both, as Monroe was confronted by team captain Reggie (played by Charles Melton). The episode also featured a sex montage for the show's leading foursome, which meant more shirtless screentime for Apa. His co-star Cole Sprouse was also shirtless for that sequence and appeared in his boxers for the scene that followed.
