The 25-year-old Borussia Dortmund star suffered a serious ankle injury on the eve of the World Cup but is on track to get back in action in the Bundesliga early in the season
Reus was cruelly ruled out of Germany's successful World Cup campaign after tearing the anterior ligament above his left ankle in a friendly against Armenia in June.
The injury was expected to sideline the 25-year-old until September but he is confident that he will soon be back in action.
"I can move quite normally and run [in] training," Reus told Bild.
"It is important for me that I will quickly [be] healthy and can play again soon."
Reus, who did not put a specific timescale on his recovery, has scored 30 goals in 62 Bundesliga appearances for Dortmund since joining from Borussia Monchengladbach two years ago.
He has been linked with moves to several big European clubs over the summer, including Manchester United and Liverpool, but Dortmund are determined to hold on to their star man, whose contract runs until 2017.
