You can only use your legs, chest and head to touch the ball, which means unless you have Abby Wambach's forehead, you're going to have to execute some bicycle kicks.
The sport is popular all over Asia, and the name is a neat combination of a Malay word "Sepak" -- or "kick" -- and a Thai word "Takraw" -- which roughly translates to "ball." (The ball usually is made of rubber or rattan.) Takraw is not too big in the U.S., though a group of college students in California organized a team in the mid-1980s. There was even a U.S. contingent at the World Championships in 1989. The Americans didn't fare all that well. And can you blame them?
