 The fitness boom of the 1980s led to one of the biggest leaps in the evolution of the bikini . According to Mills , " The leg line became superhigh , the front was superlow , and the straps were superthin . " Women 's magazines used terms like " Bikini Belly " , and workout programs were launched to develop a " bikini @-@ worthy body " . The tiny " fitness @-@ bikinis " made of lycra were launched to cater to this hardbodied ideal . Movies like Blue Crush and TV reality shows like Surf Girls have merged the concepts of bikini models and athletes together , further accentuating the toned body ideal .
