4x4 Interval Training Routine Helps Keep You Young

Researchers at the Norwegian University of Science and Technology have shown that a 4x4 Interval Training Routine can help you stay fit and trim, especially through your elderly years.

Their studies have shown that this exercise routine can help 50 year olds be as fit as 20 year olds who do not exercise much. In addition, this routine has been shown to be a quick and efficient way to increase your fitness level, and to maintain your fitness level.
