Of course those asian averages are due to their diets... I red those guys there in america are somewhat taller and still growing... You can say the same of the japanese: they´re 5"7 but they were like 5"3 in the WWII; since then the country has been developing very fast... I think the south koreans are taller, like 5"8 or something...
i wish i were taller but being skinny and long-limbed makes me look taller anyway. i weigh a measly 110... i've gained 3 pounds since i started lifting in feb.
i have no idea what my body type is best for... i used to play several sports but i wasn't the ideal type for any of them.
