The chin-chin is an elite body position that takes precise control of the flyer’s core muscles and leg flexibility. Once a scale and “broken” scale have been mastered, a flyer is then ready to move onto learning the chin-chin. This body position is executed by entering into a “broken” scale and placing the “pulled” foot under the flyer’s chin. At that point, the “pulled” foot will remain under the flyer’s chin, and the arms will open to a high-v position. This skill will use lower back and hamstring muscles the most. It’s important to consistently stretch to keep skills like the chin-chin.
