The students stand at one end of the gym. There are one or two students in the middle of the gym. A student in the middle calls out the name of one of the students at the end. That student has to run from one end of the gym to the other without being tagged. If tagged, he joins the students in the middle. If not tagged, he can call Bullrush which means that all the students have to run from one end of the gym to the other at the same time.
