Inside the rundown building in Kariobangi-North, it's almost entirely women and girls, all training under the watchful eye of boxing coach Alfred Analo Anjere -- founder of BoxGirls Kenya. In 14 years, more than 3,000 girls and women have taken up the sport at the centre. All started out for the same reason -- wanting to defend themselves in their gritty neighbourhoods, which are harsh worlds where poverty prevails and it is survival of the fittest.
