knee-hang-usually
the first move taught to a beginner flyer, as it is not
a release move. At the end of the first swing, the flyer
brings their knees up between their arms and hooks them
on the bar. At the start of the next swing, they let go
with their hands, arch their back, and look and reach
behind them to the catcher. When the catch is made, the
flyer lets go with their knees.
