A random youtube search for Roger Federer's newest commercial led me to this one! Apparently it only aired in Hong Kong, it features Kobe Bryant, Cristiano Ronaldo, Roger Federer, Maria Sharapova, Manny Pacquiao, and Xiang Liu.

Look at constant repetition of movements Roger and Maria repeat, even though they're at the top of their sports, they still practice the basics on a daily basis.
