Not sure if I am a good comparator for the exercise but I do 60 mins on the cross trainer 5-6 times a week, 60 mins of aerobics once a week, 20 mins weights programme once a week (yes you read that correctly), 30 mins yoga/pilates/stretches 4-5 times a week.
Today i did 20 mins weights followed by 60 mins cross trainer followed by 30 min pilates/yoga/stretches. Tomorrow will be 60 mins aerobics, sunday will be 60 mins cross trainer, monday-thursday will be 60 mins cross trainer followed by 30 min yoga/pilates/stretches, and so on.
This is why I eat well at the upper end of the limits, because 60 mins cross trainer burns about 850 cals.
If you dont feel like you can exercise then dont, there is nothing wrong with the couch potato route and still gets good results for pink.
