The original paper says that you can repeat the workout 2-3 times, time permitting, but does not state that it's required in order to get the benefits of the workout. In fact, the NY Times article[1] from May 9, 2013 that introduced many to the workout says: "Work by scientists at McMaster University in Hamilton, Ontario, and other institutions shows, for instance, that even a few minutes of training at an intensity approaching your maximum capacity produces molecular changes within muscles comparable to those of several hours of running or bike riding."
