well that and I'd really recommend doing stomach targeted exercises in addition to cardio. crunches are good, but watch your form so you dont hurt your lower back. Also when you start a cardio regimin it will often take a month or two to see results.

but good job for all the exercise! :)

That and it takes time for exercise regimens to show how they're working. But yeah, what Merchimerch said, if you want to lose tummy, you need to do exercises that target it. I can show you some of the stuff they put me through to lose tummy in guard, if you'd like (amongst other exercises they put me through...I was in quite good shape then).
