VIDEO VAULT: Roger + Maria sharpen tennis skills with Nike Training

Nike has launched a new commercial and website in Hong Kong for their Nike Training program. The spot features Roger Federer and Maria "Shriek"apova in a "behind-the-scenes" look into their training practices.

Roger is shown performing leg presses, shoulder presses, and lunges with a medicine ball while Maria sharpens her footwork and eye-hand coordination by jumping rope and grabbing at tennis balls being fed to her. Fascinating.

In addition to our tennis ballers, the spot also features stars from other sports including boxing champ Manny Pacquiao, basketball player Kobe Bryant, footballer Cristiano Ronaldo and hurdler Xiang Liu.
