Neuer missed the end of the Bundesliga season after suffering a broken metatarsal in Real Madrid's 6-3 aggregate triumph over Bayern in the UEFA Champions League quarter-finals.
With Neuer unable to play in any of Bayern's pre-season matches, Carlo Ancelotti has used Tom Starke, Sven Ulreich and teenagers Ron-Torben Hofmann and Christian Fruchtl in goal, with Bayern losing four of their last five outings.
Germany international Neuer may not be ready to face Borussia Dortmund in the DFL-Supercup this weekend, but he is expected to be fit for Bayern's first game of the Bundesliga season against Bayer Leverkusen on August 18.
"Under the guidance of goalkeeping coach Toni Tapalovic, the 31-year-old shot-stopper was able to complete his first specific goalkeeping session." a statement released on the Bayern website read.
"Neuer spent 20 minutes catching and throwing a few balls without overexerting himself."
