Once you have mastered a regular cartwheel, and then a one-handed cartwheel, you are ready to begin learning how to do an aerial.  An aerial is similar to a cartwheel, but no hands touch the mat.  These two girls have mastered the art of doing an aerial and give very clear instructions.  However, I advise that you have a professional instructor teach you.

 

I think these two girls will make excellent gymnastics instructors some day.  They articulate and demonstrate this gymnastics lesson on the steps to doing an aerial very clearly!
