I never cared for small asses. A well-defined butt, especially on a taller man, is a thing of beauty

Also, big hands, that are well-shaped and look strong (not thin and small). Working hands are where it's at!
Strong, shapely thighs are fantastic. I don't know why, but they're very attractive to me. Big arms. Wide shoulders. Strength, power, masculinity... yumm
I couldn't care less about a washboard stomach, honestly.
