Health and fitness guru Joe Wicks, best-known as "The Body Coach", is running live PE lessons online for children.
The government announced the mass closure of schools from Friday 20 March in an attempt to protect people from COVID-19.
But Wicks, who has more than three million followers on both Instagram and Facebook, is stepping in to deliver exercise classes during the pandemic.
The Body Coach made his announcement via social media on Thursday, vowing to become "the nation's PE teacher".
