Learned almost everything from Rio Olympics: Mirabai ahead of Tokyo Games

India's world record holder weightlifter Mirabai Chanu has learned her lessons from the in Rio meltdown five years ago and is now confident of doing well at the Tokyo Olympics.

Last month, Mirabai had revealed that she was "completely broken" after the failure at the 2016 Rio Olympics and talking to a psychologist helped her get back on track.

She said she has evolved as a weightlifter since the last Olympics, changing and tweaking techniques.

"I learned a lot by participating in the Rio Olympics. In fact, I have learned everything from Rio -- from my weaknesses to how to rectify them, how to improve myself in terms of training and performance in competition," Mirabai said in a video posted by Sports Authority of India (SAI) on Monday.
