To be fair, you need a very high IQ to understand the significance of Kylo Ren shirtless. The intent is extremely subtle, and without a solid grasp of Kylo Ren’s lightsaber, most of the rebels will fly right out of the rebel base on D’Qar. There’s also Rey’s opportunistic gaze, which is deftly woven from her attraction to him – her feelings draw heavily from her lack of significant male figures in her life. The fans understand this stuff – they have the intelelctual capacity to truly appreciate Kylo Ren’s six pack, to realize that they’re not just looking at a barely visible, flabby two-pack – the scene says something deep about the challenges in physical fitness that are compelling, rewarding and of COURSE attainable via the DARK SIDE.
