HI Lucy,
It means 6 sessions of 2 minutes per machine if you are using a selection of machines (which is recommended), or 6 sessions of 2 minutes on whichever machine/s you choose to use. So you will do a total of 12 minutes on this section of the workout, with a break between each 2-minute session to swap machines.
