I actually heard this on a health and fitness documentary a couple of days ago. They claimed you only need 3 minutes of interval training a day and it will have the same effect as the 2.5 hours a week you're normally supposed to spend exercising. Not sure I buy that...
But 50 minutes of it should definitely do the trick. I might even try it myself.
