In a country where women's sport is severely restricted, the Shaolin Wushu club in a part of Kabul that is home to the capital's Hazara ethnic community, is a rare exception.
She learned the sport in Iran, where she won a gold and bronze medal in competition, and she has been teaching in Kabul for about a year, encouraged by her father, with whom she trains at the club's gym.
"I am working with Afghan girls to strengthen their abilities and I love to see Afghan girls improve the way other girls have improved in the world," she said.
Martial arts of all kinds are popular in Afghanistan, but it is a notoriously hard country for women, and the girls of the Shaolin Wushu club face regular harassment and abuse in addition to the normal dangers of life in Kabul.
"The biggest challenge we faced is insecurity," said 18-year-old Zahra Timori. "Most of the time, we can't go to the club due to insecurity."
Her friend Shakila Muradi said she hoped that sport could help create a more peaceful climate in Afghanistan in defiance of the daily reality the girls face.
When possible, training goes on in a gym dominated by a poster of Hussain Sadiqi, a Hazara martial arts champion who fled to Australia in 1999 and later worked as a film stuntman.
So far, all the girls in the club are Hazara, a Persian-speaking, mainly Shi'ite group who have faced a series of attacks claimed by Islamic State militants over the past year.
He said he worries about his daughter's safety but said it was a joy to see her train other girls.
"I am really happy that I helped, encouraged and supported Sima," he said.
