This is for any of you who've ever wondered how little time you can spend exercising and still get all the perks.

 

They say you can't get more by doing less, but with fitness, sometimes all bets are off. A new study in the Journal of Psychology shows that regular interval training (even 10 one-minute sprints on a stationary bike with one-minute rests in between x 3 per week) is just as good as regular biking. In fact, to get the same results from endurance training, you'd need to do 10 hours of continuous, moderate biking over a 2-week period.

 

This is another piece of evidence in favor of high-intensity training (HIT), the kind of short bursts of exercise (flanked by short recoveries) that we do all the time in camp. In a study of young college students, this type of exercise produced the same benefits as conventional training -- while taking much less time away from busy schedules and actually letting the subjects do less exercise. And for you science dorks, on a cellular level, HIT training produced the exact same results we associate with endurance training. {Read the rest}
