Don't mess with this sisterhood.

A group of Buddhist nuns in the Indian Himalayas were encouraged to learn Kung Fu nearly 10 years ago by the leader of their 1,000-year-old sect. They're now passing on these skills during a five-day workshop, with grueling 15-hour days, to help women protect themselves from attack. The nuns train the women both on defensive and offensive tactics.

Although Buddhist nuns are not traditionally permitted to exercise, these nuns shake off the stereotype — and pass on their skills to other women.
