I'm excited to be a part of the Olympic movement again.

If I look what sport has done in my life, I don't think there's any doubt that sport can change lives.

Breaking the world record has always been in the works. I just need the right conditions and I can make it.

I'm excited to be a part of the Olympic movement again.

You take yourself to a place where you've got absolutely nothing left and then you find out you have to push yourself one more step. That's a tough place to be in.

For so long I wanted to win the gold medal.Then I won. I had to figure out what was the new motivation to take myself to that place again.

I train six to seven hours every single day. I wake up six days a week and know that it's going to be the same thing.
