The Germany international had not featured for the Bavarians since being taken off with an ankle injury in the 1-1 draw with Freiburg on August 27.
However, the 29-year-old made his return in the thrashing of the Russian outfit, replacing Toni Kroos on 71 minutes and Schweinsteiger has revealed that his gym sessions are paying dividends.
It felt OK, he told reporters. My injury is healing due to time spent in the gym. I'm glad I was able to play 20 minutes.
