That's news to me. Not saying it is wrong, but if it is a fact, it's one even reasonably informed people doesn't know. Studies (http://jap.physiology.org/content/102/4/1439.long and http://www.sciencedaily.com/releases/2010/03/100311123639.ht...) suggest that High-intensity interval training is an incredibly time efficient way to get in shape.
