Lifting weights heavier than themselves, the group of around 20 women are flexing their muscles in a country where sport has long been the domain of men.
Inside the Afghanistan Powerlifting Federation's cramped gym, Rasheda Parhiz lies on a bench wearing a tunic over sweatpants and holding a 70 kilogram (150-pound) weighted bar above her scarf-covered head.
The 40-year old began powerlifting several years ago to help lose weight.
Now 82 kilogrammes, Parhiz's ability to lift 100 kilogrammes has brought the mother of three trophies and medals in local and regional competitions, which she keeps in a plastic shopping bag in her mud-brick home.
"We are too lazy to dust them," says her 22-year-old daughter Lema, explaining why they are not displayed in the living room window next to tea sets and thermos.
"Who's interested?" Parhiz asks modestly.
Several times a week Afghanistan's female powerlifting team squeezes into a small carpeted room in Kabul where they pump iron.
Lifting weights heavier than themselves, the women are also flexing their muscles in a country where sport has long been the domain of men.
The Afghan Olympic Committee started the federation seven years ago but it has struggled to attract women, who are often discouraged from playing sport.
Powerlifting is a branch of weightlifting using the squat, bench press and dead lift techniques but without any moves which lift the weight vertically overhead.
There are 20 women on the national team compared with more than 100 in the men's squad, which also receives more official support, says Totakhail Shahpor, who has been the women's coach for the past three years after his predecessor absconded during a competition in Canada.
The 52-year-old former soldier considers it his duty to encourage and protect his female charges.
"I treat them like my daughters," Shahpor says. "If I imposed discipline like the army, the next day I would have no one left."
Sporty girls 'bad'
To keep them motivated Shahpor pushes the women to take part in competitions even though each of them only receive less than $15 (1,000 afghanis ) a month – barely enough to cover transport costs.
"Look at their shirts and trousers, they do not even have shoes," he says, pointing to Sadia Ahmadi's grey and yellow tracksuit that has a large patch on the thigh.
Ahmadi, 25, is the most successful member of the women's team, winning four gold medals at competitions in Uzbekistan, India and Kazakhstan, Shahpor says proudly.
Despite the taboos around female sport, the women claim they enjoy the backing, even encouragement, of their fathers or husbands to do powerlifting.
"My husband is happy ... he is proud of me and pushing me," says Parhiz.
But there are limits to his support, and he would probably baulk if powerlifting ever became an Olympic sport.
Lema says her father does not approve of his daughters attending public gyms, because sporty girls are considered "bad."
"He wouldn't like to see me at the Olympics," Parhiz says.
