We did this a few years ago before the 2012 london games, the gymnasts came through san jose. It was a successful experience for everyone involved. They hope for a ditto, repeat this time around. Lets rejoin jessica in down town san jose. Reporter boy, are they hoping for a repeat. Bela karolyi the famed coach told me he thinks this is the best team usa will have going to the olympics. So im out here which is dubbed gymnastics usa, in fact right out side the name of the road is changed to the road to rio. Inside, though, where the action is going to start happening in a bit. Where were going to see the 14 women competing for the five spots. There are going to be five women will make the team, three alternates, those will be the teams going for the gold. They are very, very favored to win the gold all around. Bela karolyi says he thinks it will be a clean sweep that they take all five gold medals in every event. Who are these women . Well, probably taking the top spot on that team will be simone biles. She is just little tiny thing, only 49, but she is airbound in everything shes done. Shes won three consecutive gold medal championships and she is probably considered even Mary Lou Retton said probably the best gymnast that lived. Despite that, that girl has to do chores at home. Im still normal im simone, i have to wash the dishes and do chores around the house. They always say yes in the gymnastics world you accomplished this but i have a normal life outside of gymnastics. Yep, she has to do chores. Her routines are really difficult, very technically difficult and she does this thing called the biles which is her signature floor routine. Well look for that on these olympic trials. The other fan fav is gabby douglas, defending her individual all around gold. You remember gabby, she was a surprise Gold Medalist at the london games. As of late she struggled. A lot changed. She is a lot older, she is 20 which is older for gymnastics action has grown 3 inches and had a reality show. So she struggled a little but is the comeback queen so expect good things. Its 50 years since a female gymnast won backtoback individual all around gold. Also, people to look for olympic medalist aly raceman. She went there in 2012. There are two names people are talking about, there is lori hernandez, if she makes the team would be the first latina to make an olympic gymnastic team. Madison is going to ucla in the fall, her name is talked about and ashton lockhere. Listen for those names. Those two girls neck and neck.
