wat i noticed is that none of them look happy!!!Gymnastics????????
This girl that my family knows had terrible back problems from doing gymnatics...
no! gymnastics is not bad at all! it adds flexibility to your body!
you can do really nice and good things for the body. i do gymnastics and really enjoy it! if it weren't for gymnastics my body wouldn't be this flexible! its not that they are not happy , its just when they do these moves they need to concentrate believe me i tried it! or they are thinking of the competition that might be coming soon which can be really frightening and irritating and scary and nervous! i really get nervous before competitions!
