Tumbling ??

If you go to gym twice a week you should get it pretty quickly. Your coach should be trying to lessen the spot each time you do it. I coach gymnastics and i usually ask if my kids are ready to lessen the sport, and i do it accordingly. If this is not happening you should tell your coach when you geel you are ready. Once you start lessening the spot, the rest happens pretty quickly and you should have it by the end of the school year.
