Just Four Minutes

  • There are other groups of scientists looking at even shorter bouts of exercise, he says, “but it seems like they don’t get the same results regarding the maximal oxygen uptake” as the four-minute sessions used in his experiment. Since improved maximal oxygen uptake can reliably indicate better overall cardiovascular health, he suspects that “we need a certain length of the interval to trigger” such health and fitness benefits.

    Thankfully, for those worried that a trip to the gym is an inefficient means of completing four minutes of exercise, the workout can effectively be practiced anywhere, Dr. Tjonna says. Sprint uphill for four minutes or race up multiple flights of steps. Bicycle, swim or even walk briskly, as long as you raise your heart rate sufficiently for four minutes.
A good reason to work on the O'Neill Test!
