The prevalence of Type 2 diabetes is rampant, with 2007 statistics showing 17.5 million people being affected at a price of $116 BILLION in medical expenses and $58 billion is lost productivity (and quality of life going to crap). The 2008 estimated cost of cardiovascular disease is $287 billion.
We all know how exercise is necessary for cardiovascular health and for improving insulin sensitivity.
But how much exercise do we need to find benefit?
This study took 25 sedentary, but otherwise healthy, young men and had them perform this activity:
The guys had a total of 6 sessions over a 2 week period. Each exercise session consisted of 4-6 30 second all out sprints on the stationary bike. They would then rest for 4 minutes before doing it again.
These guys did only 18 total minutes of actual exercise during the 2 week period!! This translates to an expenditure of only 250 calories each session.
Even the busiest person can fit 9 minutes a week of high intensity exercise into his or her life....
