New Delhi: Commonwealth Games gold medalist discus thrower Krishna Poonia who was out of the action for six months due to knee injury, is back in action this week with her eyes firmly set on London Olympics 2012.

Poonia also won a bronze in the Asian Games in China a month later and had been rehabilitating at the NIS at Patiala since February.

She skipped the two legs of Indian Grand Prix at Patiala (May 3 and 7) and the three legs of Asian Grand Prix in China last month.

Poonia returns to the competition in the June 11-14 National Inter-state Athletics Meet in Bangalore with an aim to make it to the Asian Championships (July 7-10) in Japan and be in top form in the World Championships (August 27-September 5) in South Korea.

"I have been at the NIS Patiala since February but I was rehabilitating from my injury. I began full training around 10 days ago and I am feeling good to be returning to throwing at the National Inter-state," Poonia said from Patiala.

"I will not push myself to limits at Bangalore and I am not setting any distance which I want to cross. I am taking this as a build up to my season which, of course, I am starting late due to the knee injury," she said.

She said her ultimate aim is to bring laurels for the country in the London Olympics.
