Based on a USA Today article (kinda reputable, don’t you think:-) “People who complain they have no time to exercise may soon need another excuse. Some experts say intense exercise sessions could help people squeeze an entire week’s workout into less than an hour. Those regimens — also called interval training — were originally developed for Olympic athletes and thought to be too strenuous for normal people. “High-intensity interval training is twice as effective as normal exercise,” said Jan Helgerud, an exercise expert at the Norwegian University of Science and Technology. “This is like finding a new pill that works twice as well … we should immediately throw out the old way of exercising.”
Helgerud goes on to say, “I’m much more afraid of people not exercising at all,” he said. “Inactivity is what’s killing us.”
