Not only is it easy to switch between the programs, but doing so is actively encouraged in the event that one program is a better fit than the other. Many gymnasts have made the transition from Junior Olympic to Xcel, and we have also seen gymnasts move in the opposite direction

There could also be an opportunity to be a walk-on in a D-3 school.
