Bayern Munich players made their return to training in small groups at Sabener Strasse on Monday.
Amid the coronavirus pandemic, the club's return to training is in line with the German Football League's (DFL) recommendation that teams took a break until April 5.
The Bundesliga was suspended on March 13 initially until April 2, but a meeting of clubs on March 31 extended the suspension to April 30 at the earliest.
Bayern will be training in the meantime, though they have asked fans to stay away from the club facilities as the players return to work.
Ahead of the session, which began in glorious sunshine, the club confirmed they would follow strict guidelines on hygiene and the distance kept between players.
"This will be done in coordination with government policy and the relevant authorities," read their statement on Sunday.
"It goes without saying that all hygiene regulations will be strictly observed."
Bayern are top of the Bundesliga table, four points clear of second-placed Borussia Dortmund.
