Thing is in the sentai footage at least, most of the female rangers are male stunt men. Tack on that many yellow rangers are male characters in the sentai.

Yeah there conundrum of what's realistic vs what you aesthetically expect to see.
Though Hasbro's female bodies tend to make them seem really petite. Characters who do hit the gym and have muscle. Their torsos should be a bit more developed.

The very last thing though. MMPR Red's helmet is just gigantic even for a guy. It's a giant motorcycle helmet.

Jason Yellow, I think the helmet isn't as small as it seems. I'm just used to thinking about Yellow's on a female body buck.


But this just come back to design. A designer would compensate for reality by just adjusting the sizes even if that would make the human head very small(or large). Like how Iron Man's legs in the MCU physically couldn't accommodate human anatomy.
