Hitting the highs with High Intensity Interval Training

Two weeks since I watched Michael Mosley on BBC's Horizon tell me that just a few minutes of high intensity exercising (going as hard and fast as I possibly could, to get my heart rate up to around 90% max) would shake my metabolism into a higher gear, and I am astonished at the results.  In just two weeks I'm feeling fitter and shedding weight faster than I ever have before. 

I'm doing it to improve my sugar metabolism and try to dodge my high family risk of Type II Diabetes but as I am dieting too it is already working very effectively to help me lose weight - especially the high-risk central "apple-shaped" obesity.  

Its changing all long standing teaching  Its painful to beat my heart rate up to about 150 and stay there for a minute before resting and then trying again, but not impossible (especially on my old pal, the X-trainer) and much more bearable than hours of slower slog.

here's one of the original papers  on it from Australia and some more research on the topic. .. and here   Lack of time is no longer an excuse as this slightly old report tells..

 .. maybe now the sun is coming out, one of these would be nice...  (helmets are there to keep bird woo off presumably ?

NB * Get your doctor to check you about before you try if you have any risk of heart disease or other health problems
