This departure involves the flyer jumping forwards onto the bar directly into an Uprise position.
It can be achieved as a two-handed departure (with the flyer being held behind by an instructor), a one-handed departure, or as a 'no-hands' departure where the flyer swings the bar and then leaps on when the bar returns to the board.
