You name it, I've listened to it. I tend to have determined a few ELEMENTS of the music that I like, much much moreso than the specific genre. I've found many people who are very passionate about music are this way. I love music with energy and fire. I love music that takes you on a wild ride where you don't know where you're going next.
By the time a young gymnast turns 5 years old, he or she can master more complex gymnastics skills if regular training and classes have been going on for a few years. Physical maturity, practice and good teaching will allow older children to master impressive gymnastics moves on all the equipment.
Most gymnasts dont have their period until they are 16-18 years old. It stunts your growth significantly, because you are pounding on your growth plates at such a young age. I have been in gymnastics since I was 1 1/2 and am now 14 years old and almost an elite level gymnast.
