Extra calories burned HIIT

[muchluv]

HIIT is promoted as a very good way to lose fat. Does anybody know how many calories are burned extra through raised metabolism? I have recently started doing 1hour on the crosstrainer at a time, and could do this 2 or 3 times a week if I want. That burns more than 700kcal, just wondered if HIIT would manage to do 700.. somehow I doubt it?

The Wiki article has some good information about it (with links to the studies), specifically the 'Benefits' subsection...

HIIT is a good option to mix in on occasion but a variety of moderate intensity, longer duration exercise leads to better long term calorie burn and maintenance-

HIIT and fast burn coupled with an injury will lead to time off and weight gain
