When researchers asked women to rate photos of men’s shirtless or tank top-clad upper bodies based upon either strength or attractiveness, the women tended to rate the strongest men as the most attractive. Of the 150 women who took part in the study, none of them preferred weaker men. This could have to do with the fact that deep down, women look for a man with the ability to provide for his future family, according to Aaron Sell, Ph.D., one of the study’s authors. Or maybe muscular physiques are just seen as hot in Australia. Who knows?
