The fastest hand–eye coordination sport around.
Also called ping pong, table tennis has over 15 million U.S. players and a massive global following. Using lightweight paddles and a small plastic ball, games are played to 11 points with rapid-fire volleys. Professional rallies can reach 70 miles per hour, making it one of the quickest reaction sports. Casual or competitive, it's played everywhere from basements to Olympic arenas.
