Teammates must attack the workout in order, and cannot perform similar tasks at the same time. All teammates start on the row . . . which means Teammate B has to wait until Teammate A has completed the 500 meter Row before he/she may begin. Teammates cannot be performing the gymnastics couplet or the run at the same time. Thus, Teammate B needs to wait until Teammate A returns from his/her run before he/she may begin the run.
