Since the French government ordered people to stay home on Tuesday, dancers have been turning to video conferencing for "collective bar practice" with former dancer and star coach Florence Clerc.
Practice is scheduled every day at 11 a.m.
"Ballet dancers have a lot of self-discipline, but we always need a teacher to motivate us," said Clerc, who left Paris for the south of France just before the country was placed under movement restrictions.
But video conferencing has its limits. "You can't jump or flip on the tiles or floorboards of a small apartment," Clerc added, saying that the risk of injury is too great.
The virtual class ends with stretching, push-ups and abdominal exercises.
