Callum Hudson-Odoi, the first Premier League star to test positive for Covid-19, was among the players who returned to limited, socially-distanced training for the first time since March.
Top-flight teams voted unanimously to step up their return to action at Monday's shareholders meeting, allowing players to train in a limited capacity as part of phase one of 'Project Restart'.
The 19-year-old England international Hudson-Odoi was pictured in a group with N'Golo Kante, Christian Pulisic, Kurt Zouma and Kepa Arrizabalaga at Chelsea's Cobham base in images released by the club on Tuesday.
He was cleared to train after a coronavirus test came back negative.
The 19-year-old tested positive for Covid-19 on the same day the Premier League announced its suspension on March 13 but two weeks later Blues head coach Frank Lampard announced the teenager had fully recovered.
