TUMBLING: Tumbling is performed on elevated runways, generally designed with fiberglass rods underneath, that help tumblers propel themselves higher than a basketball goal as they demonstrate speed, strength and skill while executing a series of acrobatic maneuvers. Explosive somersaults with multiple flips and twists are performed by the top-level contenders.
The most basic type of tumbling is a somersault (forward roll, and backward roll), a handstand or a cartwheel. The most important part of these basic tumbling skills is having your whole body stay as tight as possible, squeezing your arms, legs, core and bottom. Having a tight posture will help you in the long run for when you advance to the next skill, and it just looks especially cleaner when having the correct posture.
When you are ready to become more advanced in your tumbling, you will begin to do moves such as a roundoff, front handspring and back handspring. A roundoff is just a cartwheel, but instead of just stepping into it, you will be running and land with more power, and feet together. A front handspring is simply just being in a handstand, and instead of landing the same way you went up, you will be kicking your feet behind you. A back handspring is the same thing, but you do it backwards instead.
After you have mastered the basic tumbling skills, you can add twists, and tumble without putting your hands on the ground such as a back tuck. A full is one of the most advanced tumbling skill that you can have, and it is very difficult to achieve.
