BBC medical guru Michael Mosley(PhD) has a very interesting show about 3 minute high intensity training, and there are indeed couch potatoes that can reap huge benefits: ...research from a number of centres has shown that three minutes of HIT a week improves insulin sensitivity by an average of 24% ... Although 15% of people made huge strides (so-called "super-responders"), 20% showed no real improvement at all ("non-responders"). http://www.bbc.co.uk/news/health-17177251 http://www.bbc.co.uk/news/health-17177251
