Roll (gymnastics)
A roll is the most basic and fundamental skill in gymnastics. There are many variations in the skill. Rolls are similar to flips in the fact that they are a complete rotation of the body. although, the rotation of the roll is usually made on the ground while a flip is made in mid air with hips passing over the head and without any hands touching the ground. Rolls also help recover from a fall safely.
