Toosi’s exploits as a sprinter have made her a household name in the Islamic republic.
But now the 31-year-old is confined to her home and has even taken to training on the roof of her apartment block in a bid to stay in shape.
“I train at home, in any space I can use, like the rooftop, inside the house or even in the alley next to the apartment,” she told AFP.
“There’s a green space there, and I train there when no one is around,” said Toosi, who has 159,000 followers on Instagram.
Her apartment is in Shahr Ara, a densely populated neighbourhood of the sprawling capital where there are few open areas.
“We have to keep our strength up, because competition will start later and we eventually have to challenge.”
The novel coronavirus has claimed the lives of nearly 7,200 people in Iran, making it the deadliest outbreak in the Middle East.
The government ordered the closure of sports facilities in mid-March as part of measures aimed at containing the virus.
It has forced athletes of all disciplines to practise in Tehran’s public parks.
One group of boys has been forced to do football training in one such park, wedged between highways in the west of the capital.
“They call us asking where can they train, because all (training) fields are closed,” said goalkeeping coach Soheil Jelveh.
“We bring them over to parks while observing all health protocols and social distancing,” he told AFP.
“Wherever there is some grass we can train.”
