(NaturalNews) Recent research is indicating that traditional approaches to exercise that involve spending hours in the gym every day may not be the best way to stay strong and healthy. Interval training, a high-intensity type of workout that was originally created for Olympic athletes, may actually be twice as effective as regular exercise, and it can be done in a fraction of the time.
Most people are familiar with workout regimens that claim to build strength and endurance in mere minutes a day. Though seemingly deceptive, there may be more truth to such claims than one would have originally thought, depending on the technique. A few minutes of strenuous exercise a couple days out of the week is actually more effective than spending an hour or two every day in the gym.
According to Jan Helgerud, an exercise expert at the Norwegian University of Science and Technology, interval training is far superior to traditional exercise. She believes that everyday people should aim to do four, four-minute workout sets with three-minute recovery times in between. In order to maximize results and achieve optimal muscle response, these sets should be intense and somewhat straining to the body.
