as a guy with big biceps getting towards 40 who has put on a few pounds (not thor fat thankfully)...
lifting weights and staying in shape is about hating the man you see in the mirror, and wanting to be able to kill other men, not about anything women think
if anything, the thought that there are women thinking I look just fine not in peak shape makes me irrationally angry and makes me want to lift and diet harder out of spite - because it means my problems are on the inside where I can't hurt them
