What is the guideline for using one arm during the twizzle with both hands above shoulders?

The guideline for using one arm during the twizzle with both hands above the shoulders allows for one arm to be used if the skater is simultaneously holding the blade or boot. This flexibility is important in synchro skating as it accommodates different styles and techniques while still maintaining control and balance during the maneuver.

Allowing the skater to use one arm helps in creating dynamic positions that can enhance the visual aspect of the performance. The requirement to hold the blade or boot while using one arm also ensures that the skater maintains proper technique and safety throughout the twizzle. This approach balances artistic expression with technical precision, which is crucial in synchro skating.

The other options do not align with the guidelines, as they either restrict the positions too rigidly or eliminate the possibility of using one arm altogether, which would limit the skater's ability to express their style during the twizzle.
