This is just a *thought*.........

Perhaps (just perhaps) you are doing too much CARDIO. An hour and a half a day 6 days a week is possibly putting too much strain on your body, and it is refusing to lose weight. (I would recommend asking trainerdan or fern in the exercise forum about this, as I cannot claim to be an expert). I would limit your cardio to 45 minutes 4 days a week, keep the resistance training as long as you alternate muscle groups and see how that goes. I know you feel that your exercise is what is "keeping you from ballooning out" but are you sure that is not all in your head, a throwback from old low-calorie, high-cardio days?
