The boxing competition evokes images of punches between different boxers and the sight of blood on the ring for the unfortunate few.
Though the Olympic competition is not so gory, one can expect tough challenges to be fought within the ring.
There are 10 categories on the men's side (based on the individual mass of the boxers) and three on the women's side (being introduced for the first time in Olympics).
Boxers from different countries qualified for the Olympics based on their performances and results in the WBS Individual Championships, 2011 World Boxing Championships and qualifying events for each continent.
Countries like United States, Kazakhstan, Australia, Brazil, Great Britain and Russia are sending more than 10 boxers to participate in different categories—obviously, they will be the nations to watch at London.
The AIBA World Ranking is based on how the boxers perform in events approved by the governing body.
The rankings do tell a story, but recent performances have not gone the way the rankings show.
Let us look at each of the categories and see who are the top contenders.
