The Athletic report that these training measures have been accepted with no complaints while players remain upbeat about their current situation, despite no time frame on when football will resume.
Meanwhile, Willian has been granted leave to return to Brazil in order to be with his family – although other Premier League players have reportedly been denied similar requests by their clubs.
The 31-year-old is out of contract at the end of the season but has assured fans that he will complete the campaign with Chelsea, even if matches are scheduled beyond the expiration of his deal on June 30.
The Blues have temporarily put on hold all negotiations about contract extensions so Willian is one of four players in limbo over their status.
Willy Caballero, Olivier Giroud and Pedro are the other players affected, although the latter has already confirmed he will move on when his deal runs out.
