The Zero Mission design specifically? It's dense, thick muscle with healthy feminine body fat levels. You don't do all those somersaults without being really fit, and all that jumping means lots of explosive lower body strength. She's genetically and physically enhanced with alien DNA anyway, so she's basically got the look of a normal woman with the physiology and performance of someone on PEDs.

Trying to apply my Metroid autism in a way that is on topic was surprisingly fun. Thanks, OP.
