Gymnastics may be an event you hardly understand. It may be one that makes you wonder how a perfect score, or anything close, is possible, seeing how any little thing is deemed negative.
But one thing you can't wonder about are the participant's strength, charisma, work ethic and character.
We have seen great action over the past couple days and there are more intriguing story lines ahead.
Here are four gymnasts to watch on Day 4 of the Olympics.
Jordyn Wieber (USA)
Can Jordyn Wieber forget about not qualifying for the individual all-around event? That was a tough pill to swallow, seeing how she's one of, if not the best all-around gymnast in the world.
Her disappointing qualifying effort is something that will be difficult to ignore and move on from. Imagine training for years, in a sport with a short shelf life like gymnastics, just to see it ripped away.
Would you be able to regain your confidence? Would you be able to refocus to try to win gold for your country?
Seems like a tough challenge that will test her character. She's easily one of the gymnasts you want to watch Tuesday.
McKayla Maroney (USA)
For people who don't know what to expect or what to watch for in gymnastics, how about watching someone soar through the air at heights never seen from a woman gymnast?
Team USA's McKayla Maroney may be just a specialist who dominates the vault in ridiculous fashion, but she's an athlete who you would pay to see in action.
Maroney dabbles in the other events and does well in floor exercise, but she is mostly used as a weapon by Team USA in the vault—one of Team USA's best competitions.
Team USA is the best vaulting team in the world and Maroney is easily the best on the team. That's how great she is at that competition.
Beth Tweddle (GBR)
Beth Tweddle has her country on her back. She is representing Great Britain in London. The pressure for her to perform is extremely high as she leads her group into team battle.
Tweddle is participating in her third Olympic Games, so the experience is on her side. She uses a great uneven bars routine to separate herself from the competition. She takes chances, runs risks and pushes the limit, but she is generally rewarded for her efforts.
Viktoria Komova (RUS)
Russia's Viktoria Komova provides Russia a great opportunity for victory because she's solid in just about every event. She finished first in the all-around qualification.
Mustafina is one of the best gymnasts in the world. She's looking to be rewarded for her hard work leading up to the event.
Judging by qualification, she's well on her way.
