I'm in the minority with Mark. Continuous motion (NFHS) states .....if pivoting or stepping when fouled, may complete the usual foot or body movement in any activity while holding the ball. Shooting, Try, Tap (NFHS) states...The try starts when the player begins the motion which habitually precedes the release of the the ball.
In my opinion the player ended her dribble, started her 1st step while holding the ball, was then pushed (fouled), completed a legal jump stop and released the ball for a try.
I keep thinking would the view change if the 2nd movement was a step with the right foot (instead of the jump stop) and then the release of the ball? Is the jump stop throwing off the play? To me continuous motion says that shooting motions can start from the floor and the player still has the right to complete the usual movement.

" the true determining factor in ruling to award free throws or not is what the player is doing at the time of the foul. The player is doing one of three things: dribbling, passing or shooting."
