Transcript for Laurie Hernandez announces she is returning to gymnastics
All right, robin, can't wait for you to get upstairs. You know her as a gold medalist and samba'd her way onto "Dancing with the stars" and has a new children's book called "She's got this." Laurie Hernandez, everybody. How are you? I'm good. How are you? I'm good. You know what, you're 18 years old. You have two olympic medals. You've written two books. You have a mirror ball trophy. And this morning you have a big announcement. What is that? I am coming back into the gymnastics world. I'm currently training. For 2020 olympics? Cross your fingers for 2020. Cross our fingers. We're looking out for that. We are very confident that you got this, of course. And we love seeing you compete in 2016 and as we're watching you had this mantra where you said I got this. Yes. So what's going through your mind when you're saying that to yourself. Whenever I'm competing, I'm pretty much terrified before I go up there a so it's making sure that I can kind of calm myself down before I hop onto the equipment and for me that's a lot of self-talk and lf-preparation and when I was out there competing I said I got this and the camera really got a close-up of it and it captured this moment that I found was really important. Which is amazing because a lot of people would see your success and would think, oh, she's never nervous and especially a lot of kids out there. And now you wrote this book, "She's got this," it's about a gymnast who falls off. Yeah. Who has problems. Wants to quit. Has some setbacks. How do you keep going. I think with setbacks it's making sure that you can look for all the things that you're grateful for and also it's looking forward to see the goals have you planned and it's looking back to see how far you've come and if you can mix those two together that could be enough. But my family helped as well. Family always helps. You're talking about how far you've come. You have your own Barbie. Come on. Laurie Hernandez, have you your own Barbie. Thank you. And you tweeted that you hope to break ground -- boundaries. Did you ever think you'd hold your own Barbie. Not at all. I used to play with them and wake them up and they wouldn't argue and would just do it. Being able to have my own Barbie, my favorite part -- I have two, one is she's fully posable and can move. I like the pose she's in. Whoo. And also she has my curls which is really important. I always wanted to straighten my hair because I saw everybody had that but now I get to embrace it. You have a lot of young fans. We have some here in our audience and they want to K you a question. One of them, Bella, Bella wants to ask a question and, Bella, that is your question for Laurie? What is the biggest challenge you've had to overcome? Ooh. For gymnastics I think the biggest challenge I had to overcome was a lot of injuries. In 2014 in January I fractured my wrist while doing a skill and then in June I hurt my knee and had to get surgery. That whole year was really rough but reminded me how much I loved games that ticks and how I would work to come back even better. They're all in gymnastics. Can you teach them how to stick a landing. Put your books down. Come on, girls. We're going to stick this landing. Right here? Right here is fine. Okay. So whenever you're sticking a landing you want to make sure there knees aren't too straight and not too bend so you can bend them a little bit. Put your arms out in front and when you finish put them back to the side and pick your chin up like a queen. How about I do the Barbie pose? Pose like Barbie. That's how you do it. Laurie, thank you very much. She came bearing gifts. Everyone in the audience is going home with "She's got this" and the book is out now.
