Legal, Maybe Not Provable. Entering into an oral contract is one thing, but proving that the contract exists, or that specific terms of the contract exist, is entirely different. Oral contracts are legally dangerous, because there is no concrete record of their existence.
The classic ballet move, the pirouette, is a complete 360-degree turn performed on one leg. In a ballet, it is usually done more than one time, in a twirling motion. Leg muscles used in a pirouette are the calves, hamstrings and quadriceps.
Example: A pirouette needs both balance to allow you to get around and not fall out of your turn, or even try for multiples but it also needs the coordination of your arms closing in order to gain momentum and the coordination of your spot in order to be able to get around or even do more turns.
