Hmmmm... I used your weight in one of those calorie calculators and it said that you running at 8 miles an hour burns 841 calories an hour, so 700+ calories for 1/2 hour seems high.
On the other hand, it sounds like this is a good workout that really made you sweat. I would sure keep using the Wave (in fact, I am going to have to look into this thing!) but I wouldn't assume I could eat an additional 700+ calories on the days I used it.
How is that for non-committal?
