Chessboxing is a hybrid that combines two traditional pastimes: chess and boxing. The competitors compete in alternating rounds of chess and boxing.

The basic idea in Chessboxing is to combine the number one thinking sport with the number one fighting sport into a hybrid that demands the most of its competitors – both mentally and physically. One of the goals of this new sport is the old idea of a healthy mind in a healthy body. During a Chessboxing fight the control of aggression plays a big role.
