Old news, but always interesting. "Women have certainly never hit harder and not just on account of improved equipment. They’re stronger, bigger, faster, better trained and pushed above all by the example of the Williams sisters. Serena, glorious and musclebound, and Venus, long-limbed and tall, have redefined the sport around power. Years ago, tennis writers used to call Martina Navratilova, listed at 5-foot-8 and lean, a giantess with popping veins because other women seemed weaklings by comparison. Now most tour players would dwarf her." - Christopher Chung

Although I don't think "most" tour players would dwarf Navratilova. She's still pumped and has bigger muscles than lots of these women. - Christopher Chung

They took some pretty crazy/cool pics. - Dan Hsiao
