Simone Biles tumbles her way to a gold medal for Team U.S.A.
Of all of the gravity-defying stunts gymnasts pull, their seemingly impossible moves on the four-inch-wide balance beam are particularly daunting.
Lest anyone think it"s easy, flipping upside down on the beam is not only athletically challenging it requires intense concentration.
A snapshot of Simone Biles mid-flip, staring intensely at the beam while hovering just inches above it, during the women"s team finals proves how ridiculous these athletes are.
Look at that concentration!

Aerial photos of the beam show how small the gymnasts" margin of error is.
Carvajal"s goal seals it for Real Madrid late in extra-time | 2016 UEFA Super Cup Highlights
Cristiano Ronaldo has returned to Real Madrid training just a month after suffering sprained collateral ligament damage in his left knee.
The Portuguese sustained the injury in the first half of the Euro 2016 final against France on July 10.
It was thought that the 31-year-old would need eight weeks to recover but now it appears he is ahead of schedule.
Portuguese teammate Pepe was there to greet Ronaldo at Ciudad Real Madrid on the outskirts of the Spanish capital.

Zinedine Zidane"s side did not need Ronaldo to dispatch Sevilla 3-2 after extra-time in the UEFA Super Cup on Tuesday with Dani Carvajal scoring a superb winner.
Los Merengues face Real Sociedad in their La Liga opener on August 21, which could be circled as the game that Ronaldo returns in some capacity.

Next up is Celta Vigo at the Santiago Bernabeu on August 27.
Madrid then have a two week gap before taking on Osasuna on September 10 - which could be a wiser date to play again to ensure the former Man United star has completely recovered.

Manchester United have announced the signing of Paul Pogba in a world-record transfer from Juventus.
Pogba, 23, has signed a five-year contract with the option of a sixth season after United agreed to pay the Italian champions 105million (89m) over the course of two years.
That figure beats the estimated 85m that Real Madrid paid Tottenham for Gareth Bale in 2013 in the previous world-record deal.
Juventus revealed United could owe them a further five million euros (4.25million) if certain sporting targets are reached during the course of Pogba"s contract.
Pogba left United four years ago for a nominal fee, and went on to win four Serie A titles and the Coppa Italia twice while his reputation grew - persuading Jose Mourinho to pay a colossal sum to bring him back to Old Trafford.
"I am delighted to rejoin United," Pogba said. "It has always been a club with a special place in my heart and I am really looking forward to working with Jose Mourinho.

First our olympic gymnasts going for the gold in the all-around competition today and Amy sat down he can collusively with the ones they rely on more than their coaches, their moms. Amy is in Rio. For these five young women going for gold today everything they"ve done in their lives has led up to this moment but, you know, they are not the only ones feeling the pressure, their moms are feeling it too but could not be more proud of their girls. Three of the most ferocious fighters of the gymnastics team. Simone Biles. Masterfully put together. Bar routine eighth a stuck landing. Gabby Douglas. And Laurie Hernandez. All wowing the crowd Sunday night in qualifying rounds. We caught up with their moms between the action at the P & G family home in Rio fighting for the group gold medal. You"ve been here before. Yeah. You"ve been through all the excitement and nerves. How is Rio been for you, ngataly? I think it"s different because Gabrielle is four years older and to see the way she"s handling everything now. More settled. Move grounded. For Nelly Biles, her daughter Simone stepping into the spotlight for the first time. The pressure on Simone, does she feel it and all the commentators are saying she"s going to win five gold medals. That"s pressure. I think Simone tries real hard not to pay attention to what the expectation is of others. I believe there"s more pressure on me than on Simone because I am so nervous. I mean, I am just a wreck. I want to know what it was like when you were with your daughters and saw their commercials run for the first time. The first time I saw Simone"s commercial it really brought tears to my eyes. Oh, yeah, I can go bigger. I said she really has moves like no other. I was just overwhelmed by the beauty which she portrayed. And as their daughters prepare to compete tonight the moms are taking it all in, Laurie, the first U.S. Hispanic born gymnast to make the olympic team in 30 years. Talk about being a proud mom. Proud, very proud of Laurie and grateful for the moment. There were days I would get discouraged and she"d be like, let"s do this mom with a big smile. U.s. Women"s gymnastics team. Are they going to take home the gold? For sure. We"re contemplating it. No doubt? No doubt. No doubt. The one thing this team still need, guys, is a nickname. The 1996 gold medal team was known as the magnificent seven and you may remember the 2012 crew was called the fierce five so what happens on that floor tonight could shape what we call the ladies of 2016. But, Lara, I love this one they came up with they called glam squad, gabby, Laurie, Aly and Madison. G.l.a.m. We have two former olympic gymnasts, Dominique dawes, Mckayla Maroney, guys, so happy to hear your perspective. I"ll start with you Dominique. You"ve been there and know exactly what these girls are feeling right now. How do you think that they"re handling the pressure? What"s it like for them as they approach this massive competition. I would say the night before last night they did not get a very good sound sleep. I remember being extremely nervous before the "96 olympic games but throughout the day they"re going to do their Normal routine and eat what they normally eat and dom back and they"ll focus on certain affirmations to make sure they have the right mind-set but I guarantee those moms did not have a great night of sleep either. What was it like for your mom? I can"t watch my daughter play tennis. I"m a mother of two girls and I get nervous when my 2 1/2-year-old -- I can"t speak for my mother"s perspective but my coach was nervous. She was a huge support system to me as well. They spend more time with their coaches than their mothers. Mckayla, I want to ask. You had that game face. We love having you with us. You were a member of the 2012 team that won gold. Injuries derailed you from being at this olympics. You know these girls person personalally. How would you say that these girl, the G.L.A.M. Squad -- I love that name. What you know about them. They"re doing amazing. I talked to Aly. It"s their Normal. It"s their everyday routine and they"ll go out and do their thing. They"ll have fun and enjoy it and hopefully come home with a gold medal. What do you think they do in the moments before? I was a competitive diver. How do you control your breathing when you"re walking out there and have to look totally composed and we talked about game faces we"re seeing. How do they do it today. For myself I always relied on my faith and had a prayer in my head. I can do all things through Christ who strengthens me. Many of those girls may have the same and affirmations and prelims they were ten point as head of the nearest competition so they don"t have pressure. There"s no competitors out there that are close to them. Their biggest competition is between themselves. Yeah. You guys will be watching, I know. Definitely. So excited. They are amazing and so are you. Please come back. Be with us. We want your incite. Mckayla, give us the face. There it is. She"s not impressed. We are so impressed with you guys.
