New Delhi: Hitting gym every day? Well, a group of scientists has poured cold water on your efforts by claiming that just one intense workout a week can produce the same benefits as jogging or gymming everyday.
The technique, known as interval training, was developed for Olympic athletes.
But Jan Helgerud, of the Norwegian University of Science and Technology , reckons that the healthy formula can work for everyone.
The expert recommends four four-minute sessions of hard cycling or sprinting with a three-minute rest in between.
"High-intensity interval training is twice as effective as normal exercise," he said. "This is like finding a new pill that works twice as well. We should immediately throw out the old way of exercising."
In the study, when compared with traditional exercise, such as jogging, it was found that interval training doubled endurance, improved strength by more than 10 per cent and speed by at least five per cent.
