"I have really stepped it up in the last week," admitted Whitbread, speaking to Teamtalk.com. "But I am taking each day as it comes."
The former Portsmouth centre-back suffered a serious knee injury last November, keeping him out for the rest of the season. After battling back ready for pre-season training Adie broke down with an injury to his other knee.
He added: "I have my own targets, but nothing definite. I don't want to disappoint myself, especially after last time. I'm just taking it steadily, although I would like to be back playing some time next month.
"The most frustrating bit for me was when I came back from damaging the other knee."
When hearing in the summer that his plans for a return to action were put on hold Whits admits that his morale was at an all time low.
"I had worked really hard to get back, but then I had the disappointment of breaking down again. That was definitely the lowest I have felt in my career."
Meanwhile, fellow injury long-term victim Bas Savage has provisionally pencilled in April for his return to action.
The former Walton & Hersham player has not played a competitive game for the Royals since the last day of last season having broken down with a cruciate ligament injury in a pre-season friendly.
Reading's game with Crystal Palace, scheduled for Saturday 12th October, has been rescheduled due to international call-ups. The Selhurst Park based side will now play host to the Royals on Tuesday 26th November, kick off 8pm.
