This martial arts school and non-profit organization based in Rio de Janeiro caters to the LGBT community. Piranhas Team offers self-defense classes for female sex workers and LGBT people in response to Brazil's poor record with violence. Brazil has one of the highest rates of murder and domestic violence against LGBT individuals. Violence against women is also a pressing problem.
The martial arts school teaches Krav Maga techniques -- a system of self-defense designed for the Israel Defense Forces that combines other fighting elements such as boxing and judo.
While many gyms might offer female self-defense classes or function as fitness centers catering specifically to women, the approach of Piranhas Team is inclusive for a marginalized segment of the population, including prostitutes.
