Get ready in five minutes

Nothing sums up modern life better than the name of a current Japanese TV game show: Get up, have breakfast and get ready for work in five minutes.The new fad is for HIIT - short for High-Intensity Interval Training whereby just twelve minutes of very intense activity is supposed to be 3 every bit as beneficial as conventional exercise.It's supposed to get you fitter in a considerably shorter period of time than conventional exercise routines.Not only are activities getting 1 significantly quicker, but our assumptions are changing, too.Advocates of HIIT training claim that it can burn fat up to 450% more effectively than low-intensity exercise.They also maintain that it speeds up metabolism and so makes you burn more calories throughout the day.A recent survey suggests we now walk 10% faster than we did ten years ago.But have our personalities changed, too?
