Poonia is at number nine in the latest IAAF rankings, and all eight ahead of her have above 65m personal best, with Germany's Nadine Muller leading the chart with 68.89m.

The Indian said she had been undergoing yoga and other mental exercises during her training in the United States under 1976 Olympic champion Mac Wilkins so that she concentrates on her throw during the Olympics.

"Concentration is the most important thing to get the distance. I do yoga especially breathing exercises and meditation in the United Sates (at Portland where she had a three-month training). I also had regular discussion with Virender (her husband-cum-coach) and Mac Wilkins (at the training centre at Portland in US)," she said.

She, however, keeps away from following what the other season leaders were doing so that she does not feel the pressure.

"I don't want to follow what Nadine Muller or Sandra Perkovic or Stephanie Brown Trafton (Beijing Games gold medallist from United Sates) are doing. That will put pressure on me. I want to concentrate on my strength," she said.

"I don't want to put myself under pressure. I don't want to think that I can become the first Indian track and field athlete to win an Olympic medal. People may have expectations after my Commonwealth Games feat but for me I will be happy if I give my 100 per cent," she added.
