The Dutchman has been out for almost two months after rapturing a tendon and breaking the big toe on his right foot.
“I’m delighted I’m finally back on the training ground with my team-mates. There’s been no reaction,” 32-year-old Van Bommel told fcbayern.de.
“It’s taken a long, long time, so I’m even more pleased the healing process has gone so well and that I’m back out on the pitch again at last.”
